== Interrupts ==
Hardware interrupts uses standard ARM nested vectored interrupt controller.
Interrupts have ID 0-31. The RP2040 only uses 0-26, the rest are tied to
ground. Both cores are tied to the same interrupt lines.
*Do not enable the same interrupt on both cores*, as this leads to race
conditions.
