Detailed Description

Hardware Tick API.

RP2040 only has one tick generator, and it is part of the watchdog hardware.

The RP2350 has a dedicated Tick block that is used to supply ticks to TIMER0, TIMER1, RISC-V platform timer, Arm Cortex-M33 0 timer, Arm Cortex-M33 1 timer and the WATCHDOG block.
