PMIC PF3000 RESETBMCU signal

[marklu]

Hi

Based on PF3000 datasheet, page31(6.3.1.3) show "In the default mode, the RESETBMCU signal is internal timer based and does not monitor the regulators". Do it mean if we connect RESETBMCU to i.MX6, we can't guarantee the reset signal will be applied after each power is delivered well (power good).

If we want to deliver reset signal to CPU after each power is good, it seems PMIC will go to fault mode instead of default mode. Do we set OTP_PG_EN to 1 to achieve it? If we already set it once, do it also keep modified value for next power cycle (power on/off)?
