Bit 3
CHLN
This bit sets the data length.
1 (R/W): 8 bits
0 (R/W): 7 bits
Bit 2
PREN
This bit enables the parity function.
1 (R/W): Enable parity function
0 (R/W): Disable parity function
Bit 1
PRMD
This bit selects either odd parity or even parity when using the parity function.
1 (R/W): Odd parity
0 (R/W): Even parity
Bit 0
STPB
This bit sets the stop bit length.
1 (R/W): 2 bits
0 (R/W): 1 bit
Notes:
•
The UART3_nMOD register settings can be altered only when the UART3_nCTL.MODEN bit
= 0.
•
Do not set both the UART3_nMOD.IRMD and UART3_nMOD.CAREN bits simultaneously.

These bits set the UART3 transfer rate. For more information, refer to "Baud Rate
Generator."
Notes:
•
The UART3_nBR register settings can be altered only when the UART3_nCTL.MODEN bit = 0.
•
Do not set the UART3_nBR.FMD[3:0] bits to a value other than 0 to 3 when the
UART3_nMOD.BRDIV bit = 1.
