Clock asynchronous serial I/O (UART) modeMitsubishi microcomputersM16C / 62 GroupSINGLE-CHIP 16-BIT CMOS MICROCOMPUTERTable 1.19.6. Specifications of UART Mode (2)ItemSelect function_______ _______Specification• Separate CTS/RTS pins (UART0)_______ _______UART0 CTS and RTS pins each can be assigned to separate pins• Sleep mode selection (UART0, UART1)This mode is used to transfer data to and from one of multiple slave microcomputers• Serial data logic switch (UART2)This function is reversing logic value of transferring data. Start bit, parity bitand stop bit are not reversed.•TXD, RXD I/O polarity switchThis function is reversing TXD port output and RXD port input. All I/O datalevel is reversed.129
