The i.MX5x PM driver supports different modes of low power operations.
I'm particularly interested in the:
- STOP mode which maps to "Suspend to RAM"
- WAIT mode which maps to "Standby" mode
Does anybody know what is the recovery time needed from the low poer modes listed above to full running mode ?
Our idea is to read an ADC value each 1s. If the value is below a certain threshold we get back to WAIT (or STOP mode depending of the staus of the external PSU) mode. Are such fast (1 second) transition times even possible ? Looking at the source there should be no limitations, except for some PLL setup times.
Any thoughts, comments ?
