3.1. Addressing Capability

The V812 module works in A24/A32 mode. This implies that the module's address must be
specified in a field of 24 or 32 bits. The address modifiers codes recognized by the module are:
AM = %39
AM = %3D
AM = %09
AM = %0D
The module's Base address is fixed by 4 internal rotary switches housed on two piggy-back
boards plugged into the main printed circuit board (see Fig. 2.2).
The Base address can be selected in the range:
% 00 0000 <-> % FF 0000
% 0000 0000 <-> % FFFF 0000
The module's address lines A09÷A15 are not connected, so their content is meaningless: for
example writing to either Base + 104C or Base + 284C the same register is accessed.
