Table 1.16.4 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 function is not selected.
Note that for a period from when the UARTi operation mode is selected to when transfer starts, the TxDi
pin outputs an “H”. (If the N-channel open-drain is selected, this pin is in floating state.)
