One task period
Execution starts when Execute
changes to TRUE. Busy changes to
TRUE, Done changes to FALSE,
and Error changes to FALSE.
Execute is FALSE at the end of
execution, so Done is TRUE for one
task period and then changes to
FALSE.
Instruction processing continues to the
end even if Execute changes to FALSE
during execution (when Busy is TRUE).
Execute changed to FALSE, so Done
changes to FALSE.
Normal end. Busy changes to FALSE
and Done changes to TRUE. Error
does not change (remains FALSE).
