13.6.2 Table high speed comparison mode (M8130)

This section explains the table high speed comparison mode (high speed pattern output) of the DHSZ
instruction.
When two or more outputs should be activated at one time, use the HSCT instruction which can change up to
16 outputs.

1) Specify the head device number for the comparison table as
Because one line in the comparison table uses four devices,
2) Specify the number of lines in the comparison table as
The created table starts from the head register
3) Comparison data
Make sure that the comparison data is 32 bits.
