Item
• CLK polarity selection
• LSB first/MSB first selection
• Continuous receive mode selection
• Transfer clock output from multiple pins selection (UART1) (Note)
• Separate CTS/RTS pins (UART0) (Note)
• Switching serial data logic (UART2)
• TxD, RxD I/O polarity reverse (UART2)
Whether transmit data is output/input at the rising edge or falling edge of 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 from the receive buffer register
UART1 transfer clock can be chosen by software to be output from one of
the two pins set
UART0 CTS and RTS pins each can be assigned to separate pins
Whether to reverse data in writing to the transmission buffer register or
This function is reversing TxD port output and RxD port input. All I/O data
level is reversed.
reading the reception buffer register can be selected.
