•
For TYPE LWORd, the data from the Channel Data registers for Ports 0 and 1
OR Ports 2 and 3 are combined as a single 32 bit integer. Port 0 is the least
significant bits such that bit 0 of Port 0 becomes bit 0 and bit 15 of Port 1
becomes bit 31 of the 32 bit integer. Likewise, Port 2 is the least significant
bits such that bit 0 of Port 2 becomes bit 0 and bit 15 of Port 3 becomes bit 31
of the 32 bit integer. The specified Port must be DATA0 or DATA2. Refer to
Chapter 2 for more details.
