Select function
The clock synchronous serial I/O mode uses a transfer clock to transmit and receive data. This mode can
be selected with UART0. Table 13.1 lists the specifications of the clock synchronous serial I/O mode.
Table 13.2 lists the registers used in clock synchronous serial I/O mode and the register values set.

clock), the external clock is in the high state; if the CKPOL bit in the U0C0 register is set to “1” (transmit
data output at the rising edge and the receive data taken in at the falling edge of the transfer clock), the
external clock is in the low state.
