Table 1.19.4 lists the functions of the input/output pins during clock synchronous serial I/O mode. This
table shows the pin functions when the transfer clock output from multiple pins and the separate CTS/
RTS pins functions are not selected. Note that for a period from when the UARTi operation mode is
selected to when transfer starts, the TxDi pin outputs a “H”. (If the N-channel open-drain is selected, this
pin is in floating state.)
