Hi all


I have a question about function of PWR_BTN_SNS in SABRE-SDP.

Could you tell me following question ?



In the circuit diagram of SABR-SDP, I think that MX6_ONOFF and PWR_BTN_SNS will be low at the same time when SW1 is pushed.

Are these two signals necessary for returning from DSM ? Or is it only PWR_BTN_SNS ?



For the above confirmation, could you verify the operation after removing R22 of SABR - SDP ?



It seems that PWR_BTN_SNS is operated with active low.

How long time are required for the input Low section ?
