inserted in between EAV and SAV code. The CSI decodes and filters out the timing coding from the data
stream, thus recovering SENSB_VSYNC and SENSB_HSYNC signals for internal use.
4.9.12.2.2
The SENSB_VSYNC, SENSB_HSYNC, and SENSB_PIX_CLK signals are used in this mode. See
Figure
A frame starts with a rising edge on SENSB_VSYNC (all the timing corresponds to straight polarity of the
corresponding signals). Then SENSB_HSYNC goes to high and hold for the entire line. The pixel clock
is valid as long as SENSB_HSYNC is high. Data is latched at the rising edge of the valid pixel clocks.
SENSB_HSYNC goes to low at the end of the line. Pixel clocks then become invalid and the CSI stops
receiving data from the stream. For the next line, the SENSB_HSYNC timing repeats. For the next frame,
the SENSB_VSYNC timing repeats.
4.9.12.2.3
The timing is the same as the gated-clock mode (described in
except for the SENSB_HSYNC signal, which is not used. See
valid and will cause data to be latched into the input FIFO. The SENSB_PIX_CLK signal is inactive (states
low) until valid data is going to be transmitted over the bus.
