/* According to SKP16C26 documentation, "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:
