Bits Access Mnemonic Reset 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.
D30 R BUSY 0 Read-only busy
Reading a 1 indicates that the force operation you initiated
is in progress.
D29:08 R Not used 0 Write this field to 0.
D07:00 R/W CHAR 0 Force character
Defines the character that is forced out of the transmitter.
