SLOW (32 KHZ) CLOCK SOURCE REQUIREMENTS
The slow clock is always supplied from an external source. It is input on the SLOW_CLK pin, and can be a digital
signal in the range of VIO only. For slow clock frequency and accuracy refer to Table 14. The external slow clock
must be stable before the system exits from shut down mode.
[1] Slow clock is a fail safe input
