Internal Transmit Drive Monitor Enable - Channel_n:
This READ/WRITE bit-field is used to configure the Transmit Section of
Channel_n to either internally or externally monitor the TTIP_n and
TRING_n output pins for bipolar pulses, in order to determine whether to
declare the Transmit DMO Alarm condition.
If the user configures the Transmit Section to externally monitor the TTIP_n
and TRING_n output pins (for bipolar pulses) then the user must connect
the MTIP_n and MRING_n input pins to their corresponding TTIP_n and
TRING_n output pins (via a 270 ohm series resistor).
If the user configures the Transmit Section to internally monitor the TTIP_n
and TRING_n output pins (for bipolar pulses), the user does NOT need to
conect the MTIP_n and MRING_n input pins. This monitoring will be per-
formed internally at the TTIP_n and TRING_n pads.
0 - Configures the Transmit Drive Monitor to externally monitor the TTIP_n
and TRING_n output pins for bipolar pulses.
1 - Configures the Transmit Drive Monitor to internally monitor the TTIP_n
and TRING_n output pins for bipolar pulses.
Insert PRBS Error - Channel_n:
A "0 to 1" transition within this bit-field causes the PRBS Generator (within
the Transmit Section of Channel_n) to generate a single bit error within the
outbound PRBS pattern-stream.
