Set bias system (when the MMOTP cells are used the
bias system for the Partial mode is predefined)
Set start address of active area AA1S[7:0]; can be set in
multiples of 4
Set end address of active area AA1E[7:0] + 1; can be
set in multiples of 4
Enter Partial mode (PTLON).

When setting the addresses the following conditions must
be ensured:
Figure 8 shows how to use the Partial mode with Line
Address Order (LAO) set to logic 0. Figure 9 gives an
example of Partial mode with LAO set to logic 1, and
