FRM_SYSMOD[3:0]
System Interface Mode Associated Signaling Mode.
0000 = 2.048 Mbits/s CHI.
0001 = 4.096 Mbits/s CHI.
0010 = 8.192 Mbits/s CHI.
0100 = 19.44 Mbits/s PSB (device 0 mode).
0101 = 19.44 Mbits/s PSB (device 1 mode).
0110 = 19.44 Mbits/s PSB (device 2 mode).
1000 = SMI.
All others: Reserved.
FRM_ASM
System Interface Mode Associated Signaling Mode.
0 = CHI is configured to carry payload data only.
11
In PSB mode, transmit signaling is 3-stated, and receive sig-
naling ignored.
1 = CHI is configured to carry both payload data and signaling
information. Each time slot consists of 16 bits, where
8 bits are data and the remaining 8 bits are signaling infor-
mation. CHI must be programmed for 4.096 Mbits/s or
8.192 Mbits/s modes.
In PSB mode, transmit signaling is driven and receive signal-
ing is forwarded to the signaling block.
