RESET
Description
Power up defaults (bit always reads 0)
0 = No effect
1 = Reset registers and bits to power up default settings (bold entries)
LED Shutter Mode
0 = Shutter mode off (LED always on) (even if no motion up to 1 sec.)
1 = Shutter mode on (LED only on when the electronic shutter is open)
System Tests (bit always reads 0)
0 = No tests
1 = perform all system tests, output 16 bit CRC via Data_Out_Upper and Data_Out_Lower registers.
Note: Since part of the system test is a RAM test, the RAM 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. This operation requires substantially more time to
complete than other register transactions.
Resolution in counts per inch
0 = 400
1 = 800
Dump the pixel array through Data_Out_Upper and Data_Out_Lower, 256 bytes
0 = disabled
1 = dump pixel array
Reserved

Sleep Mode
0 = Normal, fall asleep after one second of no movement (1500 frames/s)
1 = Always awake
