Bit 6âSerial Port RTS Port Data (RTSDT): Specifies the serial port 5765 pin input/output

data. Input or output is specified by the RTSIO pin (see the description of bit 7, RTSIO, for

details). When the 5765 pin is designated as an output, the value of the RTSDT bit 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

0

1

Description

Input/output data is low-level

Input/output data is high-level

Bit 5âSerial Port CTS Port I/O (CTSIO): Specifies serial port &765 pin input/output. 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

0

1

Description

CTSDT bit value is not output to the &765 pin

CTSDT bit value is output to the &765 pin

(Initial value)

Bit 4âSerial Port CTS Port Data (CTSDT): Specifies the serial port &765 pin input/output

data. Input or output is specified by the CTSIO pin (see the description of bit 5, CTSIO, for

details). When the &765 pin is designated as an output, the value of the CTSDT bit 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

0

1

Description

Input/output data is low-level

Input/output data is high-level

Bits 3 and 2âReserved: These bits are always read as 0, and should only be written with 0.

Bit 1âSerial 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

0

1

Description

SPB2DT bit value is not output to the TxD2 pin

SPB2DT bit value is output to the TxD2 pin

(Initial value)
