The Configuration Interface enables the designer to configure mDOC H3 to operate in different
modes.
9.3
mDOC H3 uses a NOR-like interface that can easily be connected to any microprocessor bus.
With a demux interface, it requires 16 address lines, 16 data lines and basic memory control
signals (CE#, OE#, WE#), as shown in Figure 11 below. Typically, mDOC H3 can be mapped to
any free 128KB memory space (8KB address space requires less address lines).
