8.7.3
Figures 8.10 and 8.11 show examples of pin timing in hardware standby mode.
The CA pin is sampled using EXTAL2 (32.768 kHz), and a hardware standby request is only
recognized when the pin is low for two consecutive clock cycles.
The CA pin must be held low while the chip is in hardware standby mode.
Clock oscillation starts when the CA pin is driven high after the RESETP pin is driven low.
