Claim 0:
1. An integrated circuit to be coupled to an electronic circuit, the integrated circuit comprising:
a 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;

a trigger circuit configured to generate trigger signals for externally controlling the electronic circuit, the trigger circuit comprising a counter configured to count edges of the second signal or the third signal; and
a trigger signal generation circuit configured to generate second trigger signals based on current values of the counter.
