Data Type: Bit field
USAGE: Register 0x0a allows the user to change the configuration of the sensor. Shown below are
the bits, their default values, and optional values.
Field Name
Description
BIT 7
Must always be zero
LED_MODE
LED Shutter Mode
0 = Shutter mode off (LED always on)
1 = Shutter mode on (LED only on when illumination is required)
Sys Test
System Tests
0 = no tests
1 = perform all system tests, output 16 bit CRC via Data_Out_Upper and Data_Out_Lower
registers.
NOTE: The test will fail if SROM is loaded. Perform a hardware reset before executing this test.
Reload SROM after the test is completed.
NOTE: Since part of the system test is a RAM test, the RAM and SRAM will be overwritten with
the default values when the test is done. If any configuration changes from the default are
needed for operation, make the changes AFTER the system test is run. The system test takes
200ms (@24MHz) to complete.
NOTE: Do not access the Synchronous Serial Port during system test.
