PCR = PCM Clock Rate:
PSM = PCM Synchron Mode:
AIS0
AIC0
PBNR
BNR0
Note: RxDx relate to internal ELIC ports
0 = equal to PCM data rate
1 = double PCM data rate (not for mode 2)
0 = frame synchr. with falling edge,
1 = rising edge of PDC
Mode 0:
Mode 1:
Mode 2:
Mode 0, 1: AIC0 = 0: no comparison, AIC0 = 1: RXD0 == RXD1
Mode 2:
Mode 0: BNR = number of bits – 1
Mode 1: BNR = (number of bits)/2 – 1
Mode 2: BNR = (number of bits)/4 – 1

1 = Alternative Input Section: (PCM mode dependent)
1 = Alternative Input Comparison: (PCM mode dependent)
7 = Bit Number per Frame (mode dependent)
