Item

Specification

Select function

• CLK polarity selection

Whether transmit data is output/input at the rising edge or falling edge of the

transfer clock can be selected

• LSB first/MSB first selection

Whether transmission/reception begins with bit 0 or bit 7 can be selected

• Continuous receive mode selection

Reception is enabled simultaneously by a read from the receive buffer register

• Transfer clock output from multiple pins selection (UART1) (Note)

UART1 transfer clock can be chosen by software to be output from one of

the two pins set

_______ _______

• Separate CTS/RTS pins (UART0) (Note)

_______

UART0 CTS and RTS pins each can be assigned to separate pins

• Switching serial data logic (UART2)

Whether to reverse data in writing to the transmission buffer register or

reading the reception buffer register can be selected.

• TxD, RxD I/O polarity reverse (UART2)

This function is reversing TxD port output and RxD port input. All I/O data

level is reversed.

Table 1.19.4. Specifications of clock synchronous serial I/O mode (2)

_______ _______

Note: The transfer clock output from multiple pins and the separate CTS/RTS pins functions cannot be

selected simultaneously.
