Bit 12
PECAR
This bit selects the carrier modulation period.
1 (R/W): Carrier modulation during H data period
0 (R/W): Carrier modulation during L data period
Bit 11
CAREN
This bit enables the carrier modulation function.
1 (R/W): Enable carrier modulation function
0 (R/W): Disable carrier modulation function
Bit 10
BRDIV
This bit sets the UART3 operating clock division ratio for generating the transfer
(sampling) clock using the baud rate generator.
1 (R/W): 1/4
0 (R/W): 1/16
Bit 9
INVRX
This bit enables the USIN
n
input inverting function.
1 (R/W): Enable input inverting function
0 (R/W): Disable input inverting function
Bit 8
INVTX
This bit enables the USOUT
n
output inverting function.
1 (R/W): Enable output inverting function
0 (R/W): Disable output inverting function
Bit 7
Reserved
Bit 6
PUEN
This bit enables pull-up of the USIN
n
pin.
1 (R/W): Enable pull-up
0 (R/W): Disable pull-up
Bit 5
OUTMD
This bit sets the USOUT
n
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
