Bit 7: Global Receive-Idle Code (GRIC). Setting this bit causes all receive channels to be set to the idle code written to the TR.PCICR register. This bit must be set = 0 for read operations. The value in bits IAA0–IAA5 must be a valid transmit channel (01h to 20h for E1 mode; 01h to 18h for T1 mode).

Bit 6: Global Transmit-Idle Code (GTIC). Setting this bit causes all transmit channels to be set to the idle code written to the PCICR register. This bit must be set = 0 for read operations. The value in bits IAA0–IAA5 must be a valid transmit channel (01h to 20h for E1 mode; 01h to 18h for T1 mode).

GRIC	GTIC	FUNCTION
0	0	Updates a single transmit or receive channel
0	1	Updates all transmit channels
1	0	Updates all receive channels
1	1	Updates all transmit and receive channels

Bits 0 – 5: Channel Pointer Address Bits (IAA0 to IAA5). These bits select the channel to be programmed with the idle code defined in the TR.PCICR register. IAA0 is the LSB of the 5-bit channel code. Channel 1 is 01h.

Bits 0 – 7: Per-ChannelIdle-Code Bits (C0 to C7). This register defines the idle code to be programmed in the channel selected by the TR.IAAR register. C0 is the LSB of the idle code (this bit is transmitted last).
