when active, read image with register 0x1D (29)
The content of status register 2 is defined by register 0x11 (17). For all values made by more than one Byte, bit 7 is always 0.
This means only 7 Bit are transferred per Byte.
* Each access to the register triggers the function: just send the register address with no parameter.
Accessing the status register 0x11 selects the contents of the sensors status register. This allows to read out the parameters
of sensor temperature, register content, version of electronic board and camera, hours and on/off counters, digital inputs, laser
control, revision number, 32 byte of Eprom data, see the following pages.
