Uart3 Ch.n Baud-Rate Register - Epson S1C17M20 Technical Manual

Bit 6 PUEN
This bit enables pull-up of the USINn pin.
1 (R/W): Enable pull-up
0 (R/W): Disable pull-up
Bit 5 OUTMD
This bit sets the USOUTn pin output mode.
1 (R/W): Open-drain output
0 (R/W): Push-pull output
Bit 4 IRMD
This bit enables the IrDA interface function.
1 (R/W): Enable IrDA interface function
0 (R/W): Disable IrDA interface function
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 UAnMOD register settings can be altered only when the UAnCTL.MODEN bit = 0.
• Do not set both the UAnMOD.IRMD and UAnMOD.CAREN bits simultaneously.

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