Description

SCKDT

Undefined

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

SPB2IO

R/W

Serial Port Break Input/Output

Indicates input or output of the serial port TxD pin.

When the TxD pin is actually used as a port outputting

the SPB2DT bit value, the TE bit in SCSCR should be

cleared to 0.

0: SPB2DT bit value not output to TxD pin

1: SPB2DT bit value output to TxD pin

SPB2DT

Undefined

R/W

Serial Port Break Data

Indicates the input data of the RxD pin and the output

data of the TxD pin used as serial ports. Input/output is

specified by the SPB2IO bit. When the TxD pin is set to

output, the SPB2DT bit value is output to the TxD pin.

The RxD pin status is read from the SPB2DT bit

regardless of the SPB2IO bit setting. However, RxD

input and TxD output must be set in the PFC.

0: Input/output data is low level

1: Input/output data is high level
