Clock synchronous serial I/O modeMitsubishi microcomputersM16C / 62 GroupSINGLE-CHIP 16-BIT CMOS MICROCOMPUTERTable 1.19.4. Specifications of clock synchronous serial I/O mode (2)ItemSpecificationSelect function• CLK polarity selectionWhether transmit data is output/input at the rising edge or falling edge of thetransfer clock can be selected• LSB first/MSB first selectionWhether transmission/reception begins with bit 0 or bit 7 can be selected• Continuous receive mode selectionReception is enabled simultaneously by a read from the receive buffer register• Transfer clock output from multiple pins selection (UART1) (Note)UART1 transfer clock can be chosen by software to be output from one ofthe two pins set_______ _______• Separate CTS/RTS pins (UART0) (Note)_______ _______UART0 CTS and RTS pins each can be assigned to separate pins• Switching serial data logic (UART2)Whether to reverse data in writing to the transmission buffer register orreading the reception buffer register can be selected.• TxD, RxD I/O polarity reverse (UART2)This function is reversing TxD port output and RxD port input. All I/O datalevel is reversed._______ _______Note: The transfer clock output from multiple pins and the separate CTS/RTS pins functions cannot beselected simultaneously.122
