tps65910 EEPROM settings

Yegor Yefremov

Some bits in various registers are marked as EEPROM bit. How can save those bits? If I remove RTC battery, those bits get cleared. I want RTC block to be always enabled.

Hello,

The default value of the bits written "EEPROM" are defined in the EEPROM. At each OFF to ACTIVE transition, those default values are loaded in registers.

RTC is enabled in ACTIVE, SLEEP, OFF and BACKUP states, so it is always enabled as long as there is supply.

Best regards,

Flore

Hello,

What are the setting required if I will not using RTC inside of PMIC.

The factory configured default setting are only for AM335x, Is it processor specific? (Part number dependent)

I also required PMIC get started without any user input after power ON. So what is the best way of doing it.

when there is a clk connected to 32kIN pin PMIC will automatically switch from in ternal to xternal clk.

also need to make sure that CK32K_CTRL is set to 0.

Vikas,

PWRON will boot up the pmic if connced to gnd for the short duration. I guess you wanted to know that if you plug the battery the PMIC should boot wihtout any event? Right?

If so you need to make sure that you select the device with VMBHI_IT is not masked. This is an EEPROm setting can not be changed in the field.

Thanks,

Puneet
