Table 14.6 lists the I/O Pin Functions in Clock Asynchronous Serial I/O Mode. After the UART0 operating
mode is selected, the TXD0 pin outputs “H” level (If the NCH bit is set to “1” (N-channel open-drain
outputs), this pin is in a high-impedance state) until transfer starts.
1. The bits used for transmit/receive data are as follows: Bits 0 to 6 when transfer data is 7-bit long; bits
Pin name
Register
0 to 7 when transfer data is 8-bit long; bits 0 to 8 when transfer data is 9-bit long.
