Sample Programs for UART/SIO

We provide sample programs that can be used to operate UART/SIO.
Sample Programs for UART/SIO
For information about the sample programs for UART/SIO, refer to "
Setup Methods without Sample Program
How to select the operation mode
The operation mode selection bit (SMC10.MOD) is used.
Mode 0
Mode 1
Operating clock types and selection method
The clock selection bit (SMC10.CKS) is used.
