6.3.11 General Purpose Inputs or Outputs (GPO1, GPO2, and GPIO)

GPO1 and GPO2 pins are always configured as an output.

The GPIO-pin is an input/output, however, the input-functionality is only used in multi-PMIC configuration. In single-PMIC configuration, the pin can be used as an output. The state can be read by polling the bit GPIO_STATUS bit in MFP_CTRL register.

The I/O-configuration of the GPIO-pin is done by the MULTI_DEVICE_ENABLE bit in MFP_1_CONFIG register.

If configured as outputs, these pins can be used to sequence external rails. The GP(I)Os can be included in the sequence or be controlled via I2C-interface, writing to GPOx_EN respectively GPIO_EN bit in GENERAL_CONFIG register. The GPO is released high if activated.

The GPIO function is to be used if multiple TPS6522005-EP need to be synchronized, in case more rails need to be supplied. See application section on usage. See section "Multi-PMIC operation" for details.

The polarity of these pins is not changeable.
