Description
Serial Port SCIF_RTS Port Data
Specifies the serial port SCIF_RTS pin input/output
data. Input or output is specified by the RTSIO bit. In
output mode, the RTSDT bit value is output to the
SCIF_RTS pin. The SCIF_RTS 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.
0: Input/output data is low-level
1: Input/output data is high-level
Serial Port SCIF_CTS Port Input/Output
Specifies the serial port SCIF_CTS pin input/output
condition. When actually setting the SCIF_CTS pin as
a port output pin to output the value set by the CTSDT
bit, the MCE bit in SCFCR should be cleared to 0.
0: CTSDT bit value is not output to SCIF_CTS pin
1: CTSDT bit value is output to SCIF_CTS pin
Serial Port SCIF_CTS Port Data
Specifies the serial port SCIF_CTS pin input/output
data. Input or output is specified by the CTSIO bit. In
output mode, the CTSDT bit value is output to the
SCIF_CTS pin. The SCIF_CTS pin 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.
0: Input/output data is low-level
1: Input/output data is high-level
Serial Port Clock Port Input/Output
Specifies the serial port SCIF_SCK pin input/output
condition. When actually setting the SCIF_SCK pin as
a port output pin to output the value set by the SCKDT
bit, the CKE1 and CKE0 bits in SCSCR should be
cleared to 0.
0: SCKDT bit value is not output to SCIF_SCK pin
1: SCKDT bit value is output to SCIF_SCK pin
