followed by readout. The interface signals utilized in
snapshot mode are depicted in Figure 9. In snapshot
mode the start of the integration period is determined
by the externally applied EXPOSE pulse that the user
inputs to the MT9V403. The integration time is prepro-
grammed via the two-wire interface. After each frame's
integration period is complete, the readout process
commences and the FRAME_VALID, ROW_ VALID, and
DATA signals are output.

trolled only by changing the period of the user sup-
plied EXPOSE pulse train. The frame synchronization
waveforms for snapshot mode are shown in Figure 9.
