DESCRIPTION
Line Rate Selection:
Selects the line rate as well as the input clock frequency at the
CKREFP/N pins.
Unused
Serial/Parallel Interface Selection:
Selects the interface to the framer.
Reference Clock Frequency Selection:
Selects the reference clock frequency input at CKREFP/N pins.
Secondary values correspond to E4 frequencies. Default values depend
on the CKSL pin selection upon reset or power up.
Reserved.
Register Soft-Reset:
When this bit is set, all registers are reset to their default values. This
register bit is self-clearing.
