7) Navigate to the Serializer MAX9257A tab sheet
(Figure 5). Select Enable in the SEREN drop-down
list within the Reg04 controls if it is not enabled.
8) Select Enable in the INTEN drop-down list within
the REG08 controls of the Serializer MAX9257A
tab sheet. INTEN is changed in both MAX9258A
and MAX9257A when the INTEN drop-down list is
changed on either tab sheet.
9) From this step on, the MAX9257A and the
MAX9258A registers are no longer accessible. The
ECU can only communicate with the camera in
bypass mode because CTO is set to 0 (never come
back).
10) Navigate to the Camera Control tab sheet (Figure
6). Press the Turn On D4, Turn Off D4, Fast Blink
D4, and Slow Blink D4 buttons, respectively, to ver-
ify that the ECU is communicating to the camera
properly.
11) Press the Enable PCLK_IN/HSYNC_IN/VSYNC_IN
button to enable the pixel clock, the horizontal syn-
chronization clock, and the vertical synchronization
clock. The frequencies are displayed in the
Onboard PCLK_IN, HSYNC_IN, VSYNC_IN Status
group box.
12) Use an oscilloscope to check that CCEN is toggling
and the D1 green LED is lit up (MAX9258A LOCK
pin is asserted high).
13) Exercise different pixel clocks by selecting different
options in the Change PCLK_IN/HSYNC_IN/
VSYNC_IN group box. The selected pixel clock
