Bit 3 : HDLC-256 Software Reset (H256RST). HDLC-256 Channels 1-4 logic and registers are reset with a 0-to-1
transition in this bit. The reset is released when a zero is written to this bit.
0 = Normal Operation
1 = Reset HDLC-256 Ch 1-4
Note: HDLC-64 circuits are reset by the Framer Software Reset.
Bit 2: LIU Software Reset (LRST). LIU Channels 1-4 logic and registers are reset with a 0-to-1 transition in this
bit. The reset is released when a zero is written to this bit.
0 = Normal operation.
1 = Reset LIU channels 1–4.
Bit 1: BERT Software Reset (BRST). BERT Channels 1-4 logic and registers are reset with a 0-to-1 transition in
this bit. The reset is released when a zero is written to this bit.
0 = Normal operation.
1 = Reset BERT channels 1–4.
Bit 0: Framer Software Reset (FRST). Framers 1-4 to logic and registers are reset with a 0-to-1 transition in this
bit. The reset is released when a zero is written to this bit.
0 = Normal operation.
1 = Reset framers 1-4.

Bits 2 to 0: Silicon Revision Bits (ID[2:0]). The lower three bits of the IDR are used to display a sequential
number denoting the die revision of the chip. The initial silicon revision = “000” and is incremented with each silicon
revision. This value is not the same as the two-character device revision on the top brand of the device. This is due
to the fact that portions of the device assembly other than the silicon may change, causing the device revision
