CLKS
XCLK Select.
This pin selects either a 16x rate clock for XCLK (CLKS = 0)
or a primary line rate clock for XCLK (CLKS = 1).
XCLK Mode.
This pin must be set appropriately when using a primary line
rate clock for XCLK.
CEPT:
CLKM = 1.
DS1:
CLKM = 0.
Chip Mode.
This pin sets the chip mode for either direct logic mode or
microprocessor mode.

Receive Negative Data.
When in dual-rail (DUAL = 1: register 5, bit 4)
clock recovery mode (CDR = 1: register 5, bit 0), this signal is the received
negative NRZ data to the terminal equipment. When in data slicing mode
(CDR = 0), this signal is the raw sliced negative data of the front end.
Bipolar Violation.
When in single-rail (DUAL = 0: register 5, bit 4) clock
recovery mode (CDR = 1: register 5, bit 0), and CODE = 1 (register 5, bit 3),
this signal is asserted high to indicate the occurrence of a code violation in
the receive data stream. A code violation is a bipolar violation that is not
part of a zero substitution code. If CODE = 0, this signal is asserted to
indicate the occurrence of a bipolar violation in the received data.
