6.2.1 ACTIVE

In this example the, PMIC is already in the ACTIVE state after a normal power up event. The PMIC is kept in the ACTIVE state by setting the NSLEEP1 and NSLEEP2 bits before clearing the ENABLE_INT.


Write 0x48:0x86:0x03:0xFC    // Set NSLEEP1 and NSLEEP2 in TPS65951213
Write 0x48:0x66:0x01:0xFE    // Clear BIST_PASS_INT
Write 0x48:0x65:0x26:0xD9    // Clear all potential sources of the On Request
