If an interruptrequest flags has been set already, clear the requestflag.(9) Start the serial transmissionTransmission data → SC0TB(0x0000A10C)Reception data → Input to the SBI0 pin(9) Transmission is started by setting transmission data tothe serial 0 transmission register (SC0TB). Whentransmission is completed, the serial 0 transmissioninterrupt (SC0TIRQ) is generated. Also, reception datais stored in the SBI0sbi0 pin and the serial 0 receptioninterrupt (SC0RIRQ) is generated.Setup Procedure Description
