Configuration Registers

  • 0x5C, GPIO Configuration

GPIO configuration registers of TPS65987D allows event mapping to available GPIOs. Each GPIO output can be configured as open drain or push-pull, and use either LDO_3V3 or VDDIO as the supply. Internal pullup and pulldown resistors for each GPIO can also be configured using configuration register. Note that some of the GPIOs that are pre-configured in the firmware for specific event can’t be changed using the Application Customizer tool.
