13.8.3
Figures 13.10 and 13.11 show signal timings in hardware standby mode. Since the signal on the
CA pin is sampled at the timing of EXTAL_RTC, clock should be input to the EXTAL_RTC pin
when hardware standby mode is entered. In hardware standby mode, the CA pin must be kept low.
The clock oscillation starts if the CA pin is pulled high after the RESETP pin is brought low.
