5.1 Configuring Enable Settings

The PMIC has an Active and Standby state where rails can be enabled or disabled. The state change can be triggered by the MODE/STBY pin when configured as STBY.

  • Figure 5-1 shows the settings to be changed when using the configuration tab of the TPS65214-GUI.

  • Table 5-2 show the register fields to be written when referring to the register map.
