TXENDCB
0
Transmit Enable DC Bias Control. When TXENDCB is set to a 1,
then the DC Bias Control algorithm is enabled. When TXENDCB is
reset to a 0, then the DC Bias Control algorithm is disabled.
Reserved. These bits may be written with any value. The value writ-
ten to these bits will be returned when read. The value of these bits
will not affect device function.
Transmit Data Invert. When set to a 1, the outgoing transmit serial
data stream is inverted. When set to a 0, the outgoing transmit se-
rial data stream is not inverted.
Transmit Data Pin Control. These bits are used to control the state
of the TXDL pin when no transmit activity is present. The following
interpretations have been assigned to these bits:
