Claim 14:
15. A system, comprising:
an electronic circuit;
an integrated circuit coupled to the electronic circuit, the integrated circuit comprising a timing signal generator and a trigger circuit, the trigger circuit configured to generate trigger signals for externally controlling the electronic circuit, the timing signal generator comprising:
a tearing effect signal detector circuit configured to generate a first signal in response to detecting a first synchronization signal internal to the electronic circuit and available outside the electronic circuit,
a line counter circuit configured to generate, outside the electronic circuit, a second signal emulating a horizontal synchronization signal internal to the electronic circuit and not available outside the electronic circuit, and
a frame counter circuit configured to generate, outside the electronic circuit, a third signal emulating a vertical synchronization signal internal to the electronic circuit and not available outside the electronic circuit; and
a controller configured to independently and autonomously control operations of the electronic circuit at times triggered by the trigger signals.
