Universal Asynchronous

Receiver/Transmitter (UART)

8.1

UART0

8.1.1

Overview

UART0 is a serial port capable of asynchronous transmission. The UART0 can function in full duplex mode. Receive

data is buffered in a holding register. This allows the UART0 to start reception of a second incoming data byte before

software has finished reading the previous data byte.

When PSEL = 0



Receive pin (RX)

– UART0RX0



Transmit pin (TX)

– UART0TX0

When PSEL = 1



Receive pin (RX)

– UART0RX1



Transmit pin (TX)

– UART0TX1

: Stop Bit Select

0 = 1 bit as Stop Bit

1 = 2 bits as Stop Bit

UTTXNB

: The ninth bit data of transmitter buffer. Write the ninth bit into this location that you want to transmit

NBITEN

: Nine-BIT mode Enable Bit

0 = Eight-bit mode

1 = Nine-bit mode

UTEN

: UART Enable Bit

0 = Disable UART module

1 = Enable UART module

UTTXINV

: Transmit Invert Selection Bit

0 = Transmitter output without inverted

1 = Transmitter output inverted
