Digital Port 0 contains the positive 32 channels of the 32 differential pairs.
Digital Port 1 contains the negative 32 channels of the 32 differential pairs.
Digital Port 2 contains the 32 single-ended channels.
The following example sets the digital port 0 output states to 0xF, and returns the settings:
SHORT nStatus;
DWORD dwValue;
Gx3788PioSetPort (nHandle, GX3788_PIO_PORT0, 0xF, &nStatus);
Gx3788PioGetPort (nHandle, GX3788_PIO_PORT0, &dwValue, &nStatus);
