5.5.2 - Basic Flash Access Control
When accessing the Flash all command write addresses have to be located within the active Flash
memory space. The active Flash memory space is that logical address range which is covered by the
Flash after mapping. When using data page pointer (DPP) for addressing the Flash, make sure that
address bit A15 and A14 of the command addresses are reflected in both LSBs of the selected data page
pointer (A15 - DPPx.1 and A14 - DPPx.0).
In case of the command write addresses, address bit A14, A15 and above are don’t care. Thus, command
writes can be performed by only using one DPP register. This allow to have a more simple and compact
application software.
Another - advantageous - possibility is to use the extended segment instruction for addressing.
Note: The direct addressing mode is not allowed for write access to the Flash address/command
The following basic instruction sequences show examples for different addressing possibilities.
Principle example of address generation for Flash commands and registers:
When using data page pointer (DPP0 is this example)

When using the extended segment instruction:

register. Be aware that the C compiler may use this kind of addressing. For write accesses to
Flash module always the indirect addressing mode has to be selected.
