Writing PowerDown modes to EEPROM?

Is it possible to write power down modes for each channel to EEPROM? It appears to me that there is no function to change eep_[ch].pd but that is all I would need to do before calling analogWrite with b_eep = true?

Thanks, writing vref, power down mode, and gain to eeprom is missing now. I will add a flag if writing to reg or eep to selectXxxx() APIs.

selectPowerDown(PWR_DOWN a, PWR_DOWN b, PWR_DOWN c, PWR_DOWN d) can write power-down mode, but it does not affect EEPROM. To write to EEPROM, you need to use Sequential Write or Single Write. Please take a look at the specification section around 5.5 for more details.
