is one. To optimize the bandwidth, the codec path should be enabled only when a capture is
required.
In grayscale mode, the input data stream is stored in memory without any processing. The 12-bit
data, which represent the grayscale level for the pixel, is stored in memory one or two pixels per
word, depending on the GS_MODE bit in the ISI_CR2 register. The codec datapath is not avail-
able when grayscale image is selected.
A frame rate counter allows users to capture all frames or 1 out of every 2 to 8 frames.
The two data timings using horizontal and vertical synchronization and EAV/SAV sequence syn-
chronization are shown in
In the VSYNC/HSYNC synchronization, the valid data is captured with the active edge of the
pixel clock (ISI_PCK), after SFD lines of vertical blanking and SLD pixel clock periods delay pro-
grammed in the control register.
The ITU-RBT.656-4 defines the functional timing for an 8-bit wide interface.
There are two timing reference signals, one at the beginning of each video data block SAV
(0xFF000080) and one at the end of each video data block EAV(0xFF00009D). Only data sent
between EAV and SAV is captured. Horizontal blanking and vertical blanking are ignored. Use of
the SAV and EAV synchronization eliminates the ISI_VSYNC and ISI_HSYNC signals from the
interface, thereby reducing the pin count. In order to retrieve both frame and line synchronization
properly, at least one line of vertical blanking is mandatory.
