Fields

PARITY

This register is used to configure the parity check mode. 0:even 1:odd
PARITY_EN

Set this bit to enable uart parity check.
BIT_NUM

This registe is used to set the length of data: 0:5bits 1:6bits 2:7bits 3:8bits
STOP_BIT_NUM

This register is used to set the length of stop bit. 1:1bit 2:1.5bits 3:2bits
SW_RTS

This register is used to configure the software rts signal which is used in software flow control.
SW_DTR

This register is used to configure the software dtr signal which is used in software flow control…
TXD_BRK

Set this bit to enbale transmitter to send 0 when the process of sending data is done.
IRDA_DPLX

Set this bit to enable irda loopback mode.
IRDA_TX_EN

This is the start enable bit for irda transmitter.
IRDA_WCTL

1.the irda transmitter’s 11th bit is the same to the 10th bit. 0.set irda transmitter’s 11th bit to 0.
IRDA_TX_INV

Set this bit to inverse the level value of irda transmitter’s level.
IRDA_RX_INV

Set this bit to inverse the level value of irda receiver’s level.
LOOPBACK

Set this bit to enable uart loopback test mode.
TX_FLOW_EN

Set this bit to enable transmitter’s flow control function.
IRDA_EN

Set this bit to enable irda protocol.
RXFIFO_RST

Set this bit to reset uart receiver’s fifo.
TXFIFO_RST

Set this bit to reset uart transmitter’s fifo.
RXD_INV

Set this bit to inverse the level value of uart rxd signal.
CTS_INV
