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.
