UART Never Come Back Operation
This operation is used in an application when the
ECU completes the configuration of the MAX9257/
MAX9258 right after power-up and does not want to
access the MAX9257/MAX9258 once the video trans-
mission begins. The following procedure is an example
of one of many possible configurations:
1) Start the program or press the Reset the EVKIT
button on the ECU Control tab sheet (Figure 3).
2) If MAX9257 REM is set to high (JU25 shunt is set
across pins 1-2), press the ECU Wakes Up
MAX9257 button on the ECU Control tab sheet. If
MAX9257 REM is set to low (JU25 shunt is set
across pins 2-3), skip this step.
3) Navigate to the Deserializer MAX9258 tab sheet
(Figure 4). Press the Read MAX9258 & 9257 button
to refresh the current register values on the GUI.
4) Keep the four Write Both 9258&9257 checkboxes
checked.
5) Set t STO and t ETO on both the MAX9258 and
MAX9257 to expected values. Note that the t STO
and t ETO times are based on the pixel clock
(PCLK_IN) time. For example, if PCLK_IN is 30MHz,
set STODIV to 1024 and STOCNT to 0, t STO =
(1024 x 1/30)μs ≈ 34μs. Set ETODIV to 1024 and
ETOCNT to 4, t ETO = (1024 x 5/30)μs ≈ 170μs.
6) Set other MAX9258 registers as desired.
