11. SERIAL INTERFACE FUNCTION
The serial interface function provides two 6-channel serial interfaces.
Up to four channels can be used at the same time.
(1) Asynchronous serial interface (UART0 and UART1): 2 channels
(2) Clocked serial interface (CSI0 to CSI3): 4 channels
Caution UART0 and CSI0 share a pin, as do UART1 and CSI1. One or the other of each pair can be
selected via a register (ASIM00, ASIM10).
11.1 Asynchronous Serial Interfaces 0, 1 (UART0, UART1)
{
Transfer rate
150 bps to 76800 bps (using the dedicated baud rate generator when the internal system clock is
33 MHz)
Maximum 4.125 Mbps (using the
φ
/2 clock when the internal system clock is 33 MHz)
{
Full duplex communications
On-chip receive buffer (RXBn)
{
2-pin configuration
TXDn: Transmit data output pin
RXDn: Receive data input pin
{
Receive error detection functions
Parity error
Framing error
Overrun error
{
Interrupt sources: 3 types
Receive error interrupt (INTSERn)
Receive completion interrupt (INTSRn)
Transmission completion interrupt (INTSTn)
{
The character length of transmission/reception data is specified by the ASIMn0 and ASIMn1 registers.
{
Character length
7, 8 bits
9 bits (when adding an expansion bit)
{
Parity function: odd, even, 0, none
{
Transmission stop bit: 1, 2 bits
{
On-chip dedicated baud rate generator
{
Serial clock (SCKn) output function
