Internal Transmit Drive Monitor Enable - Channel_n:
This READ/WRITE bit-field is used to configure the Trans-
mit 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 Trans-
mit 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 make sure that he/she has con-
nected the MTIP_n and MRING_n input pins to their corre-
sponding TTIP_n and TRING_n output pins (via a 274 ohm
series resistor).
If the user configures the Transmit Section to internally
monitor the TTIP_n and TRING_n output pins (for bipolar
pulses) then the user does NOT need to make sure that the
MTIP_n and MRING_n input pins are connected to the
TTIP_n and TRING_n output pins (via series resistors).
This monitoring will be performed right at the TTIP_n and
TRING_n output pads.
0 - Configures the Transmit Drive Monitor to externally mon-
itor the TTIP_n and TRING_n output pins for bipolar pulses.
1 - Configures the Transmit Drive Monitor to internally mon-
itor the TTIP_n and TRING_n output pins for bipolar pulses.
