PWREN to last voltage stable

174(1)

1. This value is programmable in the Power Management Unit. By default, at POR, is set to the maximum of

174 ms.

Last voltage stable to LVI(2)

2. The LVI signal has effect during the boot only if the LVIEn bit is set.



If the LVIEn bit is set, the t4 timing, if respected, is the minimum timing that ensures that the PMU FSM

reaches the ON state.



If the LVIEn bit is set and an LVI event occurs before the timing t2, the PMU FSM directly moves back to

the STAND-By state without reaching the ON state.
