/* According to SKP16C26 documention, "SIO/UART1 pins are used for communication
* between the SKP16C26 board kernel and KD30 Debugger through the ICD. Do not
* connect these pins to any other circuit, as UART1 cannot be used in the user
* program. For details, please see ICD (RTA-FoUSB-MON) User Manual on Target M16C
* ROM Monitor Resources or related ICD application notes."
*
* However, the schematic appears to show that SIO/UART2 is actual connection.
* To be safe, we will error out on either selection:
