Bit Bit Name
Initial
value R/W Description
3 SCKIO 0 R/W SCK Port Input/Output
Indicates the input or output of SCK pin. When SCK pin
is used as port outputting the SCKDT bit, the CKE1,
CKE0 bit of serial control register (SCSCR) should be
set to 0.
0: Not output the SCKDT bit to SCK pin
1: Output the SCKDT bit to SCK pin
2 SCKDT 0 R/W SCK Port Data
Indicates the data of SCK pin used as port. Input/output
is specified by SCKIO bit. When output, the value of
SCKDT bit is outputted to SCK pin. Whenever input or
output, SCK pin status is read from SCKDT bit.
However Port Function of PFC (Pin Function Controller)
must be set to SCK input/output.
0: Input/output data is low level
1: Input/output data is high level
1 SPB2IO 0 R/W Serial Port Break Input/Output
Indicates the input or output of TxD pin. When TxD pin
is used as port outputting the SPB2DT bit, the TE bit of
serial control register (SCSCR) should be set to 0.
0: Not output the SPB2DT bit to TxD pin
1: Output the SPB2DT bit to TxD pin
0 SPB2DT 0 R/W Serial Port Break Data
Indicates the input data of RxD pin and the output data
of TxD pin used as port. Output of TxD pin is specified
by SPB2IO bit. When output, the value of SPB2DT bit is
outputted to TxD pin. Whenever input or output, RxD
pin status is read from SPB2DT bit. However Port
Function of PFC (Pin Function Controller) must be set
to TxD output and RxD input.
0: Input/output data is low level
1: Input/output data is high level
