Enable automatic assertion of
RW
0_h
bypass (equivalent to BYPASS=1)
when an input signal is detected
with a rate below MADI.
Forces the equalizer core and
RW

DC-restore into Bypass mode when
set to 1. No equalization occurs in
this mode.

Enable Dynamic Power Mode.
RW
0_h
Control bit overrides default when
CUSTOM_DYN_PWR_MODE_
ENABLE is set to 1.
When set to 1, overrides the
Dynamic Power Mode with value
RW
0_h
specified by parameter
CUSTOM_DYN_PWR_MODE. When
set to 0 Dynamic Power Mode will
default to disabled.
