Command Control(Block 9902)
The block 9902 identification code is used by the processor to enable a set of
commands that have their enable code set to 4 or 5 (one shot). The value
referenced by the address associated with the command, Enable DB Address,
will be set to -1 to enable the command for a one-shot (enable code 5) or
continuous (enable code 4) execution. After the command is executed, the
module resets the register to 0 to disable the command for the one-shot mode.
The format for this command block is shown in the following table.
