Bit 6—Serial Port RTS Port Data (RTSDT): Specifies the serial port 5765 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 5765 pin. The 5765 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
Description
0
1
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 &765 pin input/output
condition. When the &765 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
Description
0
1
CTSDT bit value is not output to &765 pin
CTSDT bit value is output to &765 pin
(Initial value)
Bit 4—Serial Port CTS Port Data (CTSDT): Specifies the serial port &765 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 &765 pin. The &765 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
Description
0
1
Input/output data is low-level
Input/output data is high-level
Bits 3 and 2—Reserved: These bits are always read as 0, and should only be written with 0.
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
Description
0
1
SPB2DT bit value is not output to the TxD2 pin
SPB2DT bit value is output to the TxD2 pin
(Initial value)
