16. Serial Communication Interface with FIFO (SCIF)
Bit 6—Serial Port RTS Port Data (RTSDT): Specifies the serial port RTS2 pin input/output
data. Input or output is specified by the RTSIO bit (see the description of bit 7, RTSIO, for
details). In output mode, the RTSDT bit value is output to the RTS2 pin. The RTS2 pin value is
read from the RTSDT bit regardless of the value of the RTSIO bit. The initial value of this bit
after a power-on reset or manual reset is undefined.
Bit 6: RTSDT
0
1
Description
Input/output data is low-level
Input/output data is high-level
Bit 5—Serial Port CTS Port I/O (CTSIO): Specifies the serial port CTS2 pin input/output
condition. When the CTS2 pin is actually set as a port output pin and outputs the value set by the
CTSDT bit, the MCE bit in SCFCR2 should be cleared to 0.
Bit 5: CTSIO
0
1
Description
CTSDT bit value is not output to CTS2 pin
CTSDT bit value is output to CTS2 pin
(Initial value)
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 bit (see the description of bit 5, CTSIO, for
details). In output mode, the CTSDT bit value 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
0
1
Description
Input/output data is low-level
Input/output data is high-level
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
Description
Shows that the value of the SCKDT bit is not output to the SCK2 pin
(Initial value)
Shows that the value of the SCKDT bit is output to the SCK2 pin.
