- The platform management unit (PMU) processor supports up to twelve GPIO pins
that are configurable within MIO bank 501. MIO[31:26] can be configured as PMU
inputs, and MIO[37:35] can be configured as PMU
outputs.Note: MIO[34:32] are reserved on the K24 SOM for power management functions.
- The PMU GPIOs are used for a variety of critical systems functions like watchdog timers and power management related signals.
- When not used by the PMU, these signals can be used as regular MIO pins.
