2.10 Multi PMIC Config

The TPS65219 allows to synchronize multiple devices, in case more rails are required to be supplied. The GPIO (pin#16) is an input/output digital pin, however, the input-functionality is only used in multi-PMIC configuration. The I/O-configuration of the GPIO-pin is done by the MULTI_DEVICE_ENABLE bit in MFP_1_CONFIG register. The table below shows the default multi-device register setting. For more information about the TPS65219 multi-PMIC operation, please refer to the device data sheet available on ti.com.
