2.8 LPAR4 [20H 27H]: Parallel data readout
Function: This command reads the parallel data of the designated program. When the
program number is 0, it reads out the data from the buffer RAM. When the
program has any number from 1001 to 2000, the command reads out from
the fixed data. When the program number is 9999, the command reads the
data from the command work RAM.
