12.2 Asynchronous Serial Interface (UART0 and UART1)
The asynchronous serial interface (UART0 and UART1) has the following features.
{
Two modes
Operation stop mode (used when serial transfers are not performed to enable a reduction in power
consumption)
Asynchronous serial interface mode
{
Full-duplex transmission
{
2-pin configuration
TXD0 and TXD1: Transmit data output pins
RXD0 and RXD1: Receive data input pins
{
3 types of interrupt sources
Receive error interrupt (INTSRE0 and INTSRE1)
Receive end interrupt (INTSR0 and INTSR1)
Transmit end interrupt (INTST0 and INTST1)
{
Character length: 7 bits/8 bits
{
Parity function: Odd, even, 0, none
{
Transmission stop bit: 1 bit/2 bits
{
On-chip baud rate generator
