■ Program example for UART
●
Processing description
• Perform serial transmit/receive operation using communication functions of the UART.
• P45/SCK, P44/SO and P43/SI pins are used for communication.
• Set a transmission speed of 150 baud by the internal baud rate generator.
• A character "13
H
" is transmitted from the SO pin and triggers the operation by interrupt.
• The baud rate is set with the main clock oscillation frequency (F
CH
) of 5 MHz
