The digital inputs in the response message are packed as one input per bit of
the data field. Status is indicated as 1=ON; 0=OFF. The LSB of the first data byte
contains the input addressed in the query. The other inputs follow toward the
high order end of this byte, and from low order to high order in subsequent
bytes.
Example
: reading 4 DI statuses (starting address is 0000H). Use 6 channels.
