DIRECTION=low_falling, MODE=level
4 GPIO powerup events can be configured to wake the chip up from a low power state. The pwrups are level/edge sensitive and can be set to trigger on a high/rising or low/falling event The number of gpios available depends on the package option. An invalid selection will be ignored source = 0 selects gpio0 . . source = 47 selects gpio47 source = 48 selects qspi_ss source = 49 selects qspi_sd0 source = 50 selects qspi_sd1 source = 51 selects qspi_sd2 source = 52 selects qspi_sd3 source = 53 selects qspi_sclk level = 0 triggers the pwrup when the source is low level = 1 triggers the pwrup when the source is high
| SOURCE | |
| ENABLE | Set to 1 to enable the wakeup source. Set to 0 to disable the wakeup source and clear a pending wakeup event. If using edge detect a latched edge needs to be cleared by writing 1 to the status register also. |
| DIRECTION | 0 (low_falling): undefined 1 (high_rising): undefined |
| MODE | Edge or level detect. Edge will detect a 0 to 1 transition (or 1 to 0 transition). Level will detect a 1 or 0. Both types of event get latched into the current_pwrup_req register. 0 (level): undefined 1 (edge): undefined |
| STATUS | Status of gpio wakeup. Write to 1 to clear a latched edge detect. |
| RAW_STATUS | Value of selected gpio pin (only if enable == 1) |
