Module address

The rotary dials for the address were set by the factory to be 32 bit addressing with "e" and "e" on the last dials.

We would like to use 24 bit addressing so lets set the first two dials to "ee". The last two dials should also be set to something non-zero in order to permit 32 bit addressing. The MVME-6100 board only has a small amount of 32 bit VME addressing space mapped to the MVME's address space.

               VME                             CPU
    A24   0x000000-0xffffff           0x90000000-0x90ffffff
    A32   0x08000000-0x11ffffff       0x80000000-0x89ffffff

If you set the last two dials to 0 8 then the addressing will look like

    c792Init 0xee0000     (for A24 addressing)

or

    c792Init 0x08ee0000   (for A32 addressing)

Data banks

The ADC module library will send the entire block over unless you set the ADC for sparcification.

Assuming we read all 32 channels then the data block will look like
