Bit 6: RTSDT

Bit 5—Serial Port CTS Port I/O (CTSIO): Specifies the serial port
condition. When the
CTSDT bit, the MCE bit in SCFCR2 should be cleared to 0.
Bit 5: CTSIO
0
1
Bit 4—Serial Port CTS Port Data (CTSDT): Specifies the serial port
data. Input or output is specified by the CTSIO bit (see the description of bit 5, CTSIO, for
details). In output mode, the CTSDT bit value is output to the
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
0
1
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.
