loopback mode. In loopback mode,
the transmit pin is forced high.
Reserved bits. Not used.
Request to send.
Set by user to force the RTS output to 0.
Cleared by user to force the RTS
output to 1.
Data terminal ready.
Set by user to force the DTR output to 0.

Data ready.
Description
Set automatically if COMTX and the shift
register are empty. This bit indicates that
the data has been transmitted, that is, no
more data is present in the shift register.
Cleared automatically when writing to
COMTX.
Set automatically if COMTX is empty.
COMTX can be written as soon as this bit
is set, the previous data might not have
been transmitted yet and can still be
present in the shift register.
Cleared automatically when writing to
COMTX.
Set when P1.0/IRQ1/SIN/T0 pin is held
low for more than the maximum word
length.
Set when the stop bit is invalid.
Parity error.
Set when a parity error occurs.
Set automatically if data are overwritten
before being read.
Set automatically when COMRX is full.
Cleared by reading COMRX.
