CTS/RTS function select bit (Note 1)
0 : CTS function is selected.
1 : RTS function is selected.
Transmit register empty flag
0 : Data is present in the transmit register. (Transmission is in progress.)
1 : No data is present in the transmit register. (Transmission is completed.)
CTS/RTS enable bit (Note 2)
0 : CTS, RTS function is enabled.
1 : CTS, RTS function is disabled.
UART receive interrupt mode select bit
0 : Reception interrupt
1 : Reception error interrupt
CLK polarity select bit (This bit is used in the clock synchronous serial I/O mode.) (Note 3)
0 : At the falling edge of a transfer clock, transmit data is output;
at the rising edge, receive data is input.
When not in transfer, pin CLK’s level is “H”.
1 : At the rising edge of a transfer clock, transmit data is output;
at the falling edge, receive data is input.
When not in transfer, pin CLK’s level is “L”.
Transfer format select bit (This bit is used in the clock synchronous serial I/O mode.) (Note 3)
0 : LSB (Least Significant Bit) first
1 : MSB (Most Significant Bit) first

Notes 1: Valid when the CTS/RTS enable bit = “0”.
2: Fix this bit to “1” in UART1 transmit/receive control register 0. (UART1 is not equipped with the CTS/RTS function.)
3: Fix this bit to “0” in UART mode or when serial I/O is invalid.
4: Valid in UART mode.
