The following pages contain some working sheets to facilitate the programming of the
EPIC. For several tasks (i.e. initialization, time slot switching, ...) the corresponding
registers are summarized in a way the programmer gets a quick overview on the
registers he has to use.
8.1.1
Semiconductor Group
PCM Interface
PMOD
PMD0..1 = PCM Mode, 00 = 0, 01 = 1, 10 = 2
PCR = PCM Clock Rate:
PSM = PCM Synchron Mode:
AIS0..1 = Alternative Input Section: (PCM mode dependent)
AIC0..1 = Alternative Input Comparison: (PCM mode dependent)
PBNR
BNR0..7 = Bit Number per Frame (mode dependent)
®
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
