R/W
Transmit Section ON - Channel n
This READ/WRITE bit-field is used to turn on or turn off the Transmit
Driver associated with Channel n on a per channel basis. If the user
turns on the Transmit Driver, then Channel n will transmit DS3, E3 or
STS-1 pulses on the line via the TTIP_n and TRING_ n output pins.
Conversely, if the user turns off the Transmit Driver (for channel n),
the TTIP_n and TRING_n output pins will be tri-stated.
0 - Shuts off the Transmit Driver associated with Channel n and tri-
states the TTIP_n and TRING_ n output pins.
1 - Turns on the Transmit Driver associated with Channel n.

The master TxON control (pin # P4)
must
be in a high state
(logic 1) for this operation to turn on any channel.

Channel n Interrupt Enable Bit:
This READ/WRITE bit is used to:
To enable Channel n for Interrupt Generation at the Channel
Level
To disable all Interrupts associated with Channel n within the
XRT73R12
This is a "master" enable bit for
each
channel. This bit allows
control on a per channel basis to signal the Host of selected error
conditions.
If a bit is cleared, no interrupts from that channel will be sent to
the Host via the INT.
If the bit is set (logic 1), any generated interrupt in channel n that
has been enabled in the Interrupt Enable register (IERn) for the
channel will activate the INT pin to the Host.
0 - Disables all Channel n related Interrupts.
1 - Enables Channel n-related Interrupts. The user
must enable
individual Channel n related Interrupts at the source level, before
they are can generate an interrupt.
