DESCRIPTION
Indicates current transmitter terminate condition. If transmitter is
disabled by remote terminate, the condition can be shown by this
bit.
1b: Disabled by remote terminate.
0b: The transmitter can transmit data normally.
Reset to 0b.
Remote TX Disable.
1b: If transmitter has sent XOFF message or RTS message, then
0b: otherwise
Reset to 0b.
When receiving a XON/XOFF character from a remote
transmitter, this bit is set to ‘1’. Otherwise, this bit is set to ‘0’.
The bit is read-clear.
If the Xoff/Special Character Interrupt is enabled, the Xoff
Detect status is also reflected in the Interrupt Status Register
(Priority Level 6).
1b: Event true
0b: Event false
Reset to 0b.
DTR is inactive, and then it is enabled.
