LM73 / software reset sequence

K.Yaita
Guru 29690 points

Hi Team,

I would like to ask about the following "software reset sequence".



I understood I should wait 14ms after writing a 1 to the Full Power Down bit.
Is it no ploblem to access I2C register during the wait period?

The background of the question is my customer considers to make 14ms wait by sending dummy I2C write commands.
Especially, what is occured if my customer writes RES1 to "1" and RES0 to "0" (word size is 13 bits) during the wait period? Should I wait 56ms in this case?

I believe nothing happens(I2C registers couldn't be accessed) during Full Power Down bit is "1" but would like to confirm just in case.

Best Regards,
Yaita / Japan disty
