Digital camera interface (DCMI)

Bit 0 CAPTURE: Capture enable

0: Capture disabled.

1: Capture enabled.

The camera interface waits for the first start of frame, then a DMA request is

generated to transfer the received data into the destination memory.

In snapshot mode, the CAPTURE bit is automatically cleared at the end of the

1st frame received.

In continuous grab mode, if the software clears this bit while a capture is

ongoing, the bit will be effectively cleared after the frame end.

Note: The DMA controller and all DCMI configuration registers should be

programmed correctly before enabling this bit.
