10. DEVICE REGISTERS
Fourteen address bits are used to control the settings of the registers. The registers control functions of the
framers, LIUs, and BERTs within the DS26519. The map is divided into 16 framers, followed by 16 LIUs and 16
BERTs. Global registers (applicable to all 16 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[13:8] determine the framer addressed.
10.1 Register Listings
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.
