Clock synchronous serial I/O mode
The clock synchronous serial I/O mode uses a transfer clock to transmit and receive data. Table 1.44 list the specifica-
tions of the clock synchronous serial I/O mode.
Note 1: "m" denotes the value 00
Note 2: If an overrun error occurs, the value of the UiRB register will be indeterminate. The IR bit of

CTS function/RTS function/CTS, RTS function not used
Transfer data length: 8-bits
When internal clock is selected (bit 3 at address 03A8
When external clock is selected (bit 3 at 03A8
To start transfer, the following criteria must be met:
-Transmit enable bit (bit 0 at 03AD
-Transmit buffer empty flag (bit 1 at 03AD
-When CTS function selected, CTS input level = "L"
Furthermore, if external clock is selected, the following requirements must also be met:
To start reception, the following requirement must be met:
Furthermore, if external clock is selected, the following requirement must be met:
When transmitting:
When receiving:
Overrun error (Note 2)
CLK polarity selection
LSB first/MSB first selection
Continuous receive mode selection

Input from CLKi pin
-CLKi polarity select bit (bit 6 at 03AC
-CLKi polarity select bit (bit 6 at 03AC
-Receive enable bit (bit 2 at 03AD
-Transmit enable bit (bit 0 at 03AD
-Transmit buffer empty flag (bit 1 at 03AD
-CLKi polarity select bit (bit 6 at 03AC
-CLKi polarity select bit (bit 6 at 03AC
-Transmit interrupt cause select bit (bit 4 at 3AD
when data transfer from UARTi transfer buffer register to UARTi transmit register is complete
-Transmit interrupt cause select bit (bit 4 at 3AD
when data transmission from UARTi transmit register is complete
-Interrupt requested when data transfer from UARTi receive register to UARTi receive buffer register is
completed.
This error occurs if the serial I/O starts receiving the next data and receives the 7th bit of the next
data before reading the UiRB register.
Whether transmit data is output/input at the rising edge or falling edge or the transfer clock can be
selected
Whether transmission/reception begins with bit 0 or bit 7 can be selected
Reception is enabled simultaneously by a read form the receive buffer register
Reverse data when writing to the transmission buffer register or reading the reception buffer register
can selected
This function reverses the TxD port output and RxD port input. All I/O data level is reversed.
