 ## Features
 
-This library enables you to use Interrupt from Hardware Timers on on RP2040-based boards such as RASPBERRY_PI_PICO, using [Earle Philhower's arduino-pico core](https://github.com/earlephilhower/arduino-pico). Support to [**Arduino-mbed RP2040** core](https://github.com/arduino/ArduinoCore-mbed) will be added in future releases.

 As **Hardware Timers are rare, and very precious assets** of any board, this library now enables you to use up to **16 ISR-based Timers, while consuming only 1 Hardware Timer**. Timers' interval is very long (**ulong millisecs**).

 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

 ## Usage
 
 Before using any Timer, you have to make sure the Timer has not been used by any other purpose.
-`Timer0, Timer1, Timer2 and Timer3` are supported for RP2040-based boards.
+`TIMER_IRQ_0, TIMER_IRQ_1, TIMER_IRQ_2 and TIMER_IRQ_3` are supported for RP2040-based boards.
