Unit Directory
The entry with key D4 in the unit directory (44Ch in this case) provides the offset for
unit dependent info:
Unit Dependent Info
And finally, the entry with key 40 (454h in this case) provides the offset for the camera
control register:
FFFF F0000000h + 3C0000h * 4 = FFFF F0F00000h
The base address of the camera control register is thus
FFFF F0F00000h.
The offset entered in the table always refers to the base address of F0F00000h.
This means that if you want to use the "DirectControl" program to read or write to a
register, the following value must be entered in the Address field:
"F0F00000h + Offset"
The following example should make this clear:
The camera has a temperature sensor. It measures the temperature and can be output at
any time in 0.1°C increments. The register with offset 82Ch is available for this. The
"Directcontrol" program can be used to read from this register.
