To write a Logic 1, the bytes written should be 0x00, 0x80, 0x00,
and 0x00. To write a Logic 0, the bytes written should be 0x00,
0x00, 0x00, and 0x00.
When the outputs are driven by the core, they are represented
as MP outputs in the SigmaStudio programming tool and are
driven directly from the DSP program in 5.23 format.
In addition, there are 12 multipurpose pin value registers that
allow the input/output data to be written to or read directly
from the control port. The corresponding addresses are listed in
T

0x00, 0x00, 0x00. The value of the auxiliary ADC is not stored
in these registers. The value of these registers can only be one of
two values: 0x00 0x00 0x00 0x00 (digital zero) or 0x00 0x80
0x00 0x00 (digital one). More information about the
multipurpose pins can be found in the AN-951 Application
Note, Using Hardware Controls with SigmaDSP GPIO Pins .
