Bit Bit Name
Initial
Value R/W Description
5 CTSIO 0 R/W CTS Port Input/Output
Indicates input or output of the serial port CTS pin.
When the CTS pin is actually used as a port outputting
the CTSDT bit value, the MCE bit in SCFCR should be
cleared to 0.
0: CTSDT bit value not output to CTS pin
1: CTSDT bit value output to CTS pin
4 CTSDT 1 R/W CTS Port Data
Indicates the input/output data of the serial port CTS
pin. Input/output is specified by the CTSIO bit. For
output, the CTSDT bit value is output to the CTS pin.
The CTS pin status is read from the CTSDT bit
regardless of the CTSIO bit setting. However, CTS
input/output must be set in the PFC.
0: Input/output data is low level
1: Input/output data is high level
3 SCKIO 0 R/W SCK Port Input/Output
Indicates input or output of the serial port SCK pin.
When the SCK pin is actually used as a port outputting
the SCKDT bit value, the CKE[1:0] bits in SCSCR
should be cleared to 0.
0: SCKDT bit value not output to SCK pin
1: SCKDT bit value output to SCK pin
2 SCKDT 0 R/W SCK Port Data
Indicates the input/output data of the serial port SCK
pin. Input/output is specified by the SCKIO bit. For
output, the SCKDT bit value is output to the SCK pin.
The SCK pin status is read from the SCKDT bit
regardless of the SCKIO bit setting. However, SCK
input/output must be set in the PFC.
0: Input/output data is low level
1: Input/output data is high level
