Module rp2040_hal::timer

Timer Peripheral

The Timer peripheral on RP2040 consists of a 64-bit counter and 4 alarms.
The Counter is incremented once per microsecond. It obtains its clock source from the watchdog peripheral, you must enable the watchdog before using this peripheral.
Since it would take thousands of years for this counter to overflow you do not need to write logic for dealing with this if using get_counter.

Each of the 4 alarms can match on the lower 32 bits of Counter and trigger an interrupt.

See Chapter 4 Section 6 of the datasheet for more details.
