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
