DESCRIPTION
Manually set the EOM vertical range, used with channel register
0x2C[6]:
00: ±100 mV
01: ±200 mV
10: ±300 mV
11: ±400 mV
1: Normal operation
1: Normal operation
1: Configures the final stage of the equalizer to be a limiting stage.
0: Normal operation, final stage of the equalizer is configured to be a
linear stage.
1: Forces signal detect HIGH, and force enables the channel. Should
not be set if bit 6 is set.
0: Normal Operation.
1: Forces signal detect LOW and force disables the channel. Should
not be set if bit 7 is set.
0: Normal Operation.
Controls the signal detect assert levels.
Controls the signal detect de-assert levels.
Driver De-emphasis Range
1: Powers down the high speed driver
0: Normal operation
Driver De-emphasis Setting[2:0]
