Table 15.6 lists the I/O Pin Functions in UART Mode. After the UARTi (i = 0 or 1) operating mode is selected, the
TXDi pin outputs “H” level (If the NCH bit is set to 1 (N-channel open-drain output), this pin is in a high-
impedance state) until transfer starts.
Pin name
1. The bits used for transmit/receive data are as follows: Bits 0 to 6 when transfer data is 7 bits long; bits 0 to 7
2. The following bits are undefined: Bits 7 and 8 when transfer data is 7 bits long; bit 8 when transfer data is 8 bits
Register
