We are using MC32PF3000A7EP PMIC in our design from imx6ul + pf3000 series.
We are trying to configure following registers but the regulator voltages are not getting configured. Following are the details.
|Register Name||Register Address||Value||Output|
|VREFDDRCTL||0X6A||0X01||Enable VREFDDR supply|
|OTP SWBST SEQ||0XBD||0X04 (100)||for setting the sequence to 4|
We are configuring it in a run time via a micro controller acting as a I2C host. I2C address for PMIC is set to 0X08 (default address).
In the circuit we are connecting the VDDOTP pin to ground since the IC is pre-programmed. I am attaching my PMIC schematics here. Please let me know to set the Functional register do we need to do any other setting in hardware or software.
