A Digital Control Port consisting of seven I/O pins is provided to access various control functions. Each
pin is user-configurable. The following control functions are available for the I/O pins:
Bi-directional Digital IO
Each of the seven pins can be configured as general purpose bi-directional digital inputs and outputs.
The polarity of the pins can also be configured. Pin 8 is the signal common for the digital I/O pins. Data
is programmed according to the following bit assignments:
