CIS0
CMD2
For IOM
FC0
COC = Clock Output Control (CMD1:CSS = 0)
CXF = CFI Transmit on Falling Edge: 0 = send on rising edge, 1 = send on falling DCL edge
CRR = CFI Receive on Rising Edge: 0 = receive on falling edge, 1 = send on rising DCL
CBN8
CBNR
CBN0
0 = PDC/PFS used for CFI,
1= DCL/FSC are inputs
1 = frame syncr. with rising edge,
0 = falling edge of DCL
if CSS = 0 ==> CMD1:CSM = PMOD:PSM !
Mode 0, 3: CIS0
Mode 1, 2: CIS0: 0 = IN0 = DU0, 1 = IN0 = DU2
Mode 1: CIS1: 0 = IN1 = DU1, 1 = IN1 = DU3
= 010 suitable for PBC, = 011 for IOM-2, = 110 IOM-2 and SLD
= 0 DCL = data rate,
= 1 DCL 2 × data rate (only mode 0 and 3 !)
