That's mandatory if you need to measure some data requiring better accuracy. It now supports 16 ISR-based Timers, while consuming only 1 Hardware Timer. Timers' interval is very long (ulong millisecs). The most important feature is they're ISR-based Timers. Therefore, their executions are not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mission-critical tasks.

+paragraph=These RPI_PICO_TimerInterrupt Hardware Timers, using Interrupt, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software timers using millis() or micros().

Timers interval is very long (ulong millisecs). The most important feature is they are ISR-based Timers. Therefore, their executions are not blocked by bad-behaving functions or tasks.

+    The RPI_PICO system timer peripheral provides a global microsecond timebase for the system, and generates
+    interrupts based on this timebase. It supports the following features:
    • A single 64-bit counter, incrementing once per microsecond
    • This counter can be read from a pair of latching registers, for race-free reads over a 32-bit bus.
    • Four alarms: match on the lower 32 bits of counter, IRQ on match: TIMER_IRQ_0-TIMER_IRQ_3

-  Now even you use all these new 16 ISR-based timers,with their maximum interval practically unlimited (limited only by
-  unsigned long miliseconds), you just consume only one RPI_PICO timer and avoid conflicting with other cores' tasks.
-  The accuracy is nearly perfect compared to software timers. The most important feature is they're ISR-based timers
-  Therefore, their executions are not blocked by bad-behaving functions / tasks.

+    The RPI_PICO system timer peripheral provides a global microsecond timebase for the system, and generates
+    interrupts based on this timebase. It supports the following features:
    • A single 64-bit counter, incrementing once per microsecond
    • This counter can be read from a pair of latching registers, for race-free reads over a 32-bit bus.
    • Four alarms: match on the lower 32 bits of counter, IRQ on match: TIMER_IRQ_0-TIMER_IRQ_3

-  Now even you use all these new 16 ISR-based timers,with their maximum interval practically unlimited (limited only by
-  unsigned long miliseconds), you just consume only one RPI_PICO timer and avoid conflicting with other cores' tasks.
-  The accuracy is nearly perfect compared to software timers. The most important feature is they're ISR-based timers
-  Therefore, their executions are not blocked by bad-behaving functions / tasks.
-  This important feature is absolutely necessary for mission-critical tasks.

+    The RPI_PICO system timer peripheral provides a global microsecond timebase for the system, and generates
+    interrupts based on this timebase. It supports the following features:
    • A single 64-bit counter, incrementing once per microsecond
    • This counter can be read from a pair of latching registers, for race-free reads over a 32-bit bus.
    • Four alarms: match on the lower 32 bits of counter, IRQ on match: TIMER_IRQ_0-TIMER_IRQ_3

-  RPi_Pico_ISR_Timer.cpp
-  For RP2040-based boards such as RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040 and GENERIC_RP2040.
-  Written by Khoi Hoang

-  Licensed under MIT license
-
-  The RPI_PICO system timer peripheral provides a global microsecond timebase for the system, and generates
-  interrupts based on this timebase. It supports the following features:
-    • A single 64-bit counter, incrementing once per microsecond
-    • This counter can be read from a pair of latching registers, for race-free reads over a 32-bit bus.
-    • Four alarms: match on the lower 32 bits of counter, IRQ on match: TIMER_IRQ_0-TIMER_IRQ_3
-
-  Now even you use all these new 16 ISR-based timers,with their maximum interval practically unlimited (limited only by
-  unsigned long miliseconds), you just consume only one RPI_PICO timer and avoid conflicting with other cores' tasks.
-  The accuracy is nearly perfect compared to software timers. The most important feature is they're ISR-based timers
-  Therefore, their executions are not blocked by bad-behaving functions / tasks.
-  This important feature is absolutely necessary for mission-critical tasks.
-
-  Based on SimpleTimer - A timer library for Arduino.

-  RPi_Pico_TimerInterrupt.h

-  Written by Khoi Hoang

-  Built by Khoi Hoang https://github.com/khoih-prog/RPI_PICO_TimerInterrupt
-  Licensed under MIT license
-
-  The RPI_PICO system timer peripheral provides a global microsecond timebase for the system, and generates
-  interrupts based on this timebase. It supports the following features:
-    • A single 64-bit counter, incrementing once per microsecond
-    • This counter can be read from a pair of latching registers, for race-free reads over a 32-bit bus.
-    • Four alarms: match on the lower 32 bits of counter, IRQ on match: TIMER_IRQ_0-TIMER_IRQ_3
-
-  Now even you use all these new 16 ISR-based timers,with their maximum interval practically unlimited (limited only by
-  unsigned long miliseconds), you just consume only one RPI_PICO timer and avoid conflicting with other cores' tasks.
-  The accuracy is nearly perfect compared to software timers. The most important feature is they're ISR-based timers
-  Therefore, their executions are not blocked by bad-behaving functions / tasks.
-  This important feature is absolutely necessary for mission-critical tasks.

-  To enable an alarm:
-  • Enable the interrupt at the timer with a write to the appropriate alarm bit in INTE: i.e. (1 << 0) for ALARM0
-  • Enable the appropriate timer interrupt at the processor (see Section 2.3.2)
-  • Write the time you would like the interrupt to fire to ALARM0 (i.e. the current value in TIMERAWL plus your desired
-    alarm time in microseconds). Writing the time to the ALARM register sets the ARMED bit as a side effect.
-  Once the alarm has fired, the ARMED bit will be set to 0 . To clear the latched interrupt, write a 1 to the appropriate bit in
-  INTR.

-  RPi_Pico_TimerInterrupt.h
-  For RP2040-based boards such as RASPBERRY_PI_PICO, ADAFRUIT_FEATHER_RP2040 and GENERIC_RP2040.
-  Written by Khoi Hoang

-
-  The RPI_PICO system timer peripheral provides a global microsecond timebase for the system, and generates
-  interrupts based on this timebase. It supports the following features:
-    • A single 64-bit counter, incrementing once per microsecond
-    • This counter can be read from a pair of latching registers, for race-free reads over a 32-bit bus.
-    • Four alarms: match on the lower 32 bits of counter, IRQ on match: TIMER_IRQ_0-TIMER_IRQ_3
-
-  Now even you use all these new 16 ISR-based timers,with their maximum interval practically unlimited (limited only by
-  unsigned long miliseconds), you just consume only one RPI_PICO timer and avoid conflicting with other cores' tasks.
-  The accuracy is nearly perfect compared to software timers. The most important feature is they're ISR-based timers
-  Therefore, their executions are not blocked by bad-behaving functions / tasks.
-  This important feature is absolutely necessary for mission-critical tasks.

-  To enable an alarm:
-  • Enable the interrupt at the timer with a write to the appropriate alarm bit in INTE: i.e. (1 << 0) for ALARM0
-  • Enable the appropriate timer interrupt at the processor (see Section 2.3.2)
-  • Write the time you would like the interrupt to fire to ALARM0 (i.e. the current value in TIMERAWL plus your desired
-    alarm time in microseconds). Writing the time to the ALARM register sets the ARMED bit as a side effect.
-  Once the alarm has fired, the ARMED bit will be set to 0 . To clear the latched interrupt, write a 1 to the appropriate bit in
-  INTR.
