VSYNC indicates when a new
image is about to start being sent out on the pixel data bus.
HREF indicates when a new
line is about to start being sent out on the pixel data bus.
PCLK indicates when there is valid pixel data on the pixel data bus.
The VIP engine latches data into the VIP buffers during the following conditions:
• On the active EDGE of VSYNC (0 = falling-edge, 1 = rising-edge), the VIP engine will count until the number of expected lines are received (i.e. any extraneous lines are ignored).
• On the active LEVEL of HREF (0 = active high, 1 = active low), the VIP engine will count until the number of expected pixels are received (i.e. any extraneous pixels are ignored).
