Bit 1—Serial Port Break I/O (SPB2IO): Specifies the serial port TxD2 pin output condition.
When the TxD2 pin is actually set as a port output pin and outputs the value set by the SPB2DT
bit, the TE bit in SCSCR2 should be cleared to 0.
Bit 1: SPB2IO

Description
SPB2DT bit value is not output to the TxD2 pin
SPB2DT bit value is output to the TxD2 pin
(Initial value)
Bit 0—Serial Port Break Data (SPB2DT): Specifies the serial port RxD2 pin input data and
TxD2 pin output data. The TxD2 pin output condition is specified by the SPB2IO bit (see the
description of bit 1, SPB2IO, for details). When the TxD2 pin is designated as an output, the value
of the SPB2DT bit is output to the TxD2 pin. The RxD2 pin value is read from the SPB2DT bit
regardless of the value of the SPB2IO bit. The initial value of this bit after a power-on reset or
manual reset is undefined.
Bit 0: SPB2DT

Description
Input/output data is low-level
Input/output data is high-level
