Bit 4—Serial Port CTS Port Data (CTSDT): Specifies the serial port CTS2 pin input/output
data. Input or output is specified by the CTSIO pin (see the description of bit 5, CTSIO, for
details). When the CTS2 pin is designated as an output, the value of the CTSDT bit is output to the
CTS2 pin. The CTS2 pin value is read from the CTSDT bit regardless of the value of the CTSIO
bit. The initial value of this bit after a power-on reset or manual reset is undefined.
Bit 4: CTSDT

Bit 3—Serial Port Clock Port I/O (SCKIO): Sets the I/O for the SCK2 pin serial port. To
actually set the SCK2 pin as the port output pin and output the value set in the SCKDT bit, set the
CKE1 and CKE0 bits of the SCSCR2 register to 0.
Bit 3: SCKIO
0
1
Bit 2—Serial Port Clock Port Data (SCKDT): Specifies the I/O data for the SCK2 pin serial
port. The SCKIO bit specified input or output. (See bit 3: SCKIO, for details.) When set for
output, the value of the SCKDT bit is output to the SCK2 pin. Regardless of the value of the
SCKIO bit, the value of the SCK2 pin is fetched from the SCKDT bit. The initial value after a
power-on reset or manual reset is undefined.
Bit 2: SCKDT
0
1
Bit 1—Serial Port Break I/O (SPB2IO): Specifies the serial port TxD2 pin output condition.
When the TxD2 pin is actually set as a port output pin and outputs the value set by the SPB2DT
bit, the TE bit in SCSCR2 should be cleared to 0.
Bit 1: SPB2IO

Shows I/O data level is HIGH
Description
SPB2DT bit value is not output to the TxD2 pin
SPB2DT bit value is output to the TxD2 pin
