Description

D31

R/W

ENABLE

0

Force transmit enable
Use this field to force the transmitter to send the character
specified in the CHAR field (D07:00). All user-specified
rules, such as bit order, parity, or number of stop bits, are
enforced.
Write a 1 to enable this field. Hardware clears the field
once the character has been transmitted. Writing a 1 to this
field when it is already a 1 has unpredictable results.

Note:

Writing a 1 to this field also clears the FORCE
field in the Interrupt Status register.
