4--7--2 Program 1: Read Program
In the following program, a single shift register is used to control data move-
ment of both data select codes and read data. A total of nine scans will be
required to move all eight units of data from the E5AF (4 data select codes
and 4 digits of read data). The data read into the PC is stored in the DM area
and output to the display from there. Data select codes (DSL) are stored in
DM 0000 to DM 0003. Data is output to the display via IR 004.
