ABORTPixel is an optional command that stops a READPixel command during its execution. It also causes pixel
integration to terminate and to enter the auto-zero/reset state. Any values that were being held in the array’s
sample/hold circuits are lost.
Encoding: 0x12: <0001_0010>
READHold is a macro command that combines both the SAMPLEInt and READPixel commands into a single
command. It is also provided as a shortcut for advanced users.
Encoding: 0x16: <0001_0110>
READHold is a macro command that combines the SAMPLEInt , READPixel, and StartInt commands into a
single command, and is provided as a shortcut for advanced users.
The register commands provide the user the capability of setting gain and offset corrections for each of the three
zones of pixels. a4–a0 refer to the register address as given in Table 2.
Encoding: 0x40 <data>: <010a4_a3a2a1a0> <d7d6d5d4_d3d2d1d0>
REGWrite writes a value into either a gain, offset, or mode register. The 5-bit address of the register is encoded
into the command byte (the first byte). A second byte, which contains the data to be written, follows the command
byte.
Encoding: 0x60: <011a4_a3a2a1a0>
REGRead reads the value previously stored in a gain, offset, or mode register. The 5-bit address of the register
is encoded into the command byte. Then, following receipt of the REGRead command, the device places the
contents of the selected register onto the SDOUT pin, LSB first. Data will be available to read 4 clocks after the
execution of the command.
