This register is read-only and gives the chip identificat ion number: 0x8232.
First row to be read out
Minimum recommended value = 0x0006.
First column to be read out
Window height (number of rows - 1)
Window widt h (number of columns - 1)
Minimum recommended value = 0x0009.
Horizontal Blanking (number of columns)
Minimum value for 0x05 = 0x0009.
Minimum recommended value for 0x05 = 0x007B (123 pixel clocks).
Vertical Blanking (number of rows -1)
Minimum recommended value = 0x0003.
Synchronize changes (copied to Reg0xF1, bit1).
0 = normal operation, update changes t o registers that aff ect image brightness (integrat ion time,
integration delay, gain, horizontal and vertical blanking, window size, row/column skip, or row
mirror) at the next f rame boundary.
1 = do not update any changes to these settings until this bit is ret urned t o “0.”
Chip Enable (copied to Reg0xF1, bit 0).
1 = normal operation.
0 = stop sensor readout. When this is returned to “ 1,” sensor readout restarts at the starting row in a
new frame. The digital power consumption can t hen also be reduced to less than 5uA by turning off
the master clock.
By setting this bit to “ 1,” the sampling and reset timing of t he pixels will be halved. This bit should
therefore only be used if the master clock frequency is 13.5 MHz or less. When this bit is set t he
minimum recommended horizontal blanking value is 17, compared to 123 when this bit is not set .
Shutter Delay will be master clocks divided by 2 when this bit is set, compared to master clocks
divided by 4 when this bit is 0.
Note: Use this register for 15 fps with 12 MHz master clock.
Allow Shutter Width to be exactly one full frame.
0 = normal operation = Maximum S hut ter Width equals the t otal number of rows - 1. If Shutter
Width exceeds the number of rows -1, the total number of rows in t he image will be increased to
Shutter Width + 1.
1 = Maximum Shutter Width equals the total number of rows. When the Shutter Width exceeds the
number of rows, the total number of rows in the image will be increased to mat ch the Shutt er Width.
Reserved.
Shift pixel clock: (11,10,9,8) = (1, x, x, x): shift pixel clock 1 clock earlier (0, 1, x, x): shift pixel clock ½
clock earlier (0, 0, 1, x): delay pixel clock by ½ clock(0, 0, 0, 1): delay pixel clock by 1 clock (0, 0, 0, 0):
no delay pixel clock (default mode).
Invert pixel clock:
0 = normal operation.
1 = invert pixel clock.
