Bits 0 to 5/Channel Pointer Address Bits (IAA0 to IAA5). IAA0 is the LSB of the 5-bit Channel Code.

Bit 6/Global Transmit Idle Code (GTIC). Setting this bit will cause all transmit idle codes to be set to the value written to the PCICR register. When using this bit, the user must place any transmit address in the IAA0 through IAA5 bits (00h –1Fh). This bit must be set = 0 for read operations.

Bit 7/Global Receive Idle Code (GRIC). Setting this bit will cause all receive idle codes to be set to the value written to the PCICR register. When using this bit, the user must place any receive address in the IAA0 through IAA5 bits (20h –3Fh). This bit must be set = 0 for read operations.

Bits 0 to 7/Per-Channel Idle Code Bits (C0 to C7). C0 is the LSB of the code (this bit is transmitted last).

The TCICE1 /2/3/4 are used to determine which of the 24 T1 or 32 E1 channels from the backplane to the T1 or E1 line should be overwritten with the code placed in the per-channel code array.
