Preliminary Specifications REV. E
Specifications in this manual are tentative and subject to change
UART0 through UART2
Table 1.26 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
TxD pin outputs a “H”. The typical clock synchronous timing diagrams are shown in Figure 1.83.
