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 SCSCR1 should be cleared to 0.

Bit 0—Serial Port Break Data (SPB0DT): Specifies the serial port RxD pin input data and TxD
pin output data. The TxD pin output condition is specified by the SPB0IO bit (see the description
of bit 1, SPB0IO, for details). When the TxD pin is designated as an output, the value of the
SPB0DT bit is output to the TxD pin. The RxD pin value is read from the SPB0DT bit regardless
of the value of the SPB0IO bit. The initial value of this bit after a power-on reset or manual reset
is undefined.

The serial port register (SCSPTR2) is a 16-bit readable/writable register that controls input/output
and data for the port pins multiplexed with the serial communication interface with FIFO (SCIF)
pins. Input data can be read from the RxD2 pin, output data written to the TxD2 pin, and breaks in
serial transmission/reception controlled, by means of bits 1 and 0. SCK2 pin data reading and
output data writing can be performed by means of bits 3 and 2. CTS2 pin data reading and output
