Item

Specification

Select function

• CLK polarity selection

Whether transmit data output/input timing is 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 automatically after the receive buffer register is

read

• Switching serial data logic (UART2)

Whether to invert data (1's complement) when writing to the

transmission buffer register or reading the reception buffer register can

be selected.

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

This function inverts the TxD port output and RxD port input. All I/O

data level is reversed.

• Transfer clock output from multiple pins selection (UART1)

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

of the two pins set
