Serial I/O
Figure GA-6. UARTi transmit/receive mode register in clock synchronous serial I/O mode (i=0,1)
Table GA-2 lists the functions of the input/output pins during clock synchronous serial I/O mode. 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.)
