Note 1: Specify the all mode control registers first and then the <RXE>.
Note 2: Do not stop the receive operation (by setting SCxMOD0<RXE> to "0") when data is being received.

Type
R
Read as "0".
R/W
Transmit data bit 8 (For only UART mode)
Writes the 9th bit of transmit data in the 9-bit UART mode.
R/W
Handshake function control (For only UART mode)
0: CTS disabled
1: CTS enabled
Controls handshake function.
Setting "1" enables handshake function using CTSx pin.
R/W
Receive control (Note1)(Note2)
0: Disabled
1: Enabled
R/W
Wake-up function (For only UART mode)
0: Disabled
1: Enabled
This function is available only at 9-bit UART mode. In other mode, this function has no meaning.
When it is enabled, interrupt is occurred only when RB9 = "1" in a 9-bit UART mode.
R/W
Specifies transfer mode.
00: I/O interface mode
01: 7-bit UART mode
10: 8-bit UART mode
11: 9-bit UART mode
R/W
Serial transfer clock (For only UART mode)
00: TMRB output
01: Baud rate generator
10: System clock (fsys)
11: External clock (SCLKx pin input)
(For the I/O interface mode, the transfer clock in I/O interface mode is selected by SCxCR<IOC>.)
