10.
Thirteen address bits are used to control the settings of the registers. The registers control functions of the framers,
LIUs, and BERTs within the DS26514. The map is divided into four framers, followed by four LIUs and four BERTs.
Global registers (applicable to all four transceivers and BERTs) are located within the address space of Framer 1.
The register details are provided in the following tables. The framer registers bits are provided for Framer 1 and
address bits A[12:8] determine the framer addressed.
10.1
The framer registers have an offset of 200 hex, the LIU registers have an offset of 20 hex, and the BERT registers
have an offset of 10 hex for each transceiver.
