- Detailed Description-Power Management Functions
The gpio block includes an internal programmable PWM generator (can be connected to any of the GPIO1_CURR1 …
GPIO4_CURR4 outputs). Its timing is defined by the following tables:

All Step Down DCDC converters and several LDOs can be directly on/off controlled by CURR3_GPIO3 or
CURR4_GPIO4. The CURR3_GPIO3 and/or CURR4_GPIO4 pin should be set to digital input mode (GPIO3Mode =
010b, GPIO4Mode = 010b) and the following register should be set accordingly:
