Input

Enable

BOOL

FALSE

A rising edge (Enable = TRUE) starts a single operation, the output Busy goes to TRUE. All other inputs are read and considered continuously. A falling edge (Enable = FALSE) aborts the operation, if BUSY=TRUE (Note: During Aborting the Busy is still TRUE). Afterwards all outputs will be reset. For executing another operation the Enable input needs to be retriggered by another rising edge!
