Bit 1—Serial Port Break I/O (SPB0IO): Specifies the serial port TxD pin output condition. When

the TxD pin is actually set as a port output pin and outputs the value set by the SPB0DT bit, the

TE bit in SCSCR should be cleared to 0.

Bit 1: SPB0IO

Description

The SPB0DT bit value is not output to the TxD pin.

(Initial value)

The SPB0DT bit value is output to the TxD pin.

Bit 0–Serial Port Break Data (SPB0DT): Specifies serial port RxD pin input data and TxD pin

output data. The TxD pin output condition is set with the SPB0IO bit (see the description of

SPB0IO above). When the TxD pin is set as an output, the value of the SPB0DT bit is output to

the TxD pin. The RxD pin value is always read from the SPB0DT bit, regardless of the value of

the SPB0IO bit. The initial value of this bit after a power-on reset is undefined.

Bit 0 : SPB0DT

Description

I/O data level is low.

(Initial value)

I/O data level is high.
