2.4 Clock Inputs
The slow clock is always supplied from an external source. It is connected to the
SLOW_CLK_IN pin number 8 and can be a digital signal with peak to peak of 0-1.8 V.
The slow clock's frequency accuracy must be 32.768 kHz
(according to the Bluetooth specification).
The Slow Clock 32.768 kHz is mandatory to start the internal controller; otherwise the module
does not start up.
