i.MX: PCA9450 registers

Contributor III


We have a question regarding the registers of PCA9450 PMIC.

1) If we change the value of register 0x09 (CONFIG1), does the pmic keep the changed value after a power cycle?

2) If other PMIC registers values are reconfigured by SW, do all the values stay the same after power cycle or do they return to the default values?

3) How do we program new PMIC default values, so they become the new values effective at each power-up (That stay retained)?

Thanks for you help!
