Purpose is to provide a mechanism to synchroneously stop filling the SPY memories across the module for debugging and diagnostic purpouses - so that all memories can be read out by the software. When a write occurs to the inhibit register and the value is 16#xxx1# (LSB set) the inhibit output signal is pulled high one clock after the event. Similarly when a write occurs and LSB is 0 the inhibit is removed

'Client' modules must all register the inhibit signal in the system domain.
