Slave Clock Mode with External 8.192 MHz and 32.768 MHz
In the slave clock mode the 8.192 MHz and the 32.768 MHz clock have to be
synchronous and phase aligned (e.g. SCLKI has been derived from CLK32 by some
external device). There is no internal synchronization between SCLKI and CLK32.
SDECI is needed for correct phase alignment of SCLKI to the internal system clock.
CLK4O is a 4.096 MHz system clock output for subsequent circuits, derived from SCLKI
