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)
UART1 transfer clock can be chosen by software to be output from one of
the two pins set
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.
