Hi, TI team:

Could you tell me what time PMIC need to take reset reaction after watchdog sets error? just reset time.

It is defined by register value?

Hi Rocky,

If I understand correctly you're referring to time shown in DS between two green lines. This time is not specified in DS but it is few internal 20MHz clock cycles meaning in range of hundreds of nanoseconds.

Hi Rocky,

Reset extension time is defined by PFSM warm reset sequence. Do you have OPN available what you're referring here?
