If any data will be transferred with Byte commands, their signals
should be connected now. Assign the signals to the remaining data
lines. All signals on a byte should go in the same direction. Record
the device signal names and pin numbers in Table 2-7 or 2-9.
Record each byte's polarity in Table 2-8.
