Line/Pixel Timing
The
programmed to work in either master or slave mode.
In both master and slave modes, pixel data output is
synchronous with PCLK (or MCLK if port is a slave),
HREF and VSYNC. The default PCLK edge for valid data
is the negative edge but may be programmed with register
COMK[4] (see
Basic line/pixel output timing is illustrated in
Figure
To minimize image capture circuitry and conserve
memory space, PCLK output can be programmed with
register COMK[5] (see
qualified by the active video period as defined by the
HREF signal. See
