CHI Common Control Register (FRM_PR46)
This register defines the common attributes of the transmit and receive CHI. The default value is 00 (hex).
Table 169. CHI Common Control Register (FRM_PR46) (68E; C8E)
CHI Transmit Control Register (FRM_PR47)
The default value of this register is 00 (hex).
Table 170. CHI Transmit Control Register (FRM_PR47) (68F; C8F)
CHI Receive Control Register (FRM_PR48)
The default value of this register is 00 (hex).

Description
Transmit CHI Bit Offset.
These 3 bits define the bit offset from TCHIFS for each trans-
mit time slot. The offset is the number of TCHICK clock periods by which the first bit is
delayed from TCHIFS.
Transmit Frame Clock Edge.
A 0 (1) enables the falling (rising) edge of TCHICK to
latch in the frame synchronization signal, TCHIFS.
Receive CHI Bit Offset.
These 3 bits define the bit offset from RCHIFS for each
received time slot. The offset is the number of RCHICK clock periods by which the first
bit is delayed from RCHIFS.
Received Frame Clock Edge.
A 0 (1) enables the falling (rising) edge of RCHICK to
latch in the frame synchronization signal, RCHIFS.

Description
Transmit Byte Offset.
Combined with FRM_PR65 bit 0 (TBYOFF6), these 6 bits define
the byte offset from TCHIFS to the beginning of the next transmit CHI frame on TCHI-
DATA.
Transmitter Clock Edge.
A 1 (0) enables the rising (falling) edge of TCHICK to clock out
data on TCHIDATA.
