13 UART
13.1 General Description
This LSI includes one channel of UART (Universal Asynchronous Receiver Transmitter), a full-duplex
communication start-stop synchronous serial interface.
For input clocks, see Chapter 6, "Clock Generation Circuit".
To use the UART, it needs to set the secondary and quartic functions of the ports 0, 3, 4, and 5.
For the port
function setting, see Chapter 17 "Port 0", Chapter 20 "Port 3", Chapter 21 "Port 4", and Chapter 22 "Port5".
If The UART is used, Set to "0" the both of DUA0 and DUA1 bit of BLKCON2 register. If the both of
these
bits
are "1", the UART is reset-state. For BLKCON2 register, see Chapter 4, "Power Management”.
