(8 kHz), DCL (1536 kHz) and BCL (768 kHz) synchronous to the received S/T frames.
In LT modes these pins are input and in LT-T mode an 1536 kHz clock synchronous to
S is output at SCLK which can be used for DCL input.
An internal clock divider provides an FSC (ACFG2.FBS=0) or BCL (ACFG2.FBS=1)
output on pin AUX5/FBOUT derived from the DCL clock. The output can be enabled via
ACFG2.A5SEL=1.
The FSC signal is used to generate the pulse lengths of the different reset sources C/I
