Simplified block diagram in CSF
The figure below shows only one acknowledgment input Ack1 and one delayed deactivation output Out1. The
circuit for Ack2 and the other delayed outputs are identical. The parameter FirstRun is also missing in the
function diagram. The mode of operation is described above.
