Detailed Descriptions and Timing Considerations
Internal HOT_RESET assert to dead circuit only. (DVCC1A &DVCC1C circuit)
When PMCCTL<PCM_ON> = 1, mode transition from normal mode to the Power Cut
mode takes a maximum of three low-frequency clock cycles (about 92 μs). During this
period, the external wake-up requests are ignored.
A maximum of 2.5low-frequency clock cycles (about 77 μs) is required for the PWE pin to
change from 0 to 1 after the wake-up interrupt is received.
After exiting the Power Cut mode, the PMCCTL<PCM_ON> bit is cleared to 0 by soft
ware to return to normal mode. To enter the Power Cut mode again, the
PMCCTL<PCM_ON> bit should be once cleared to 0 and set to 1 again. In this case, the
PMCCTL<PCM _ON> bit should be fixed at 0 for a minimum of one low-frequency clock
cycle (about 31 μs). Otherwise, the PCM may not be entered by changing its state from 1
to 0 and to 1 again.
The wake-up triggers asserted during the wake-up operation from the PCM are ignored.
When a maximum of one low-frequency clock cycle (about 31 μs) has elapsed after the
warm-up counter is expired, the DRV setting of every port is switched to the normal
setting. Then, two low-frequency clock cycles (about 62 μs) later, the internal reset signal
(Hot_Reset) is negated.
