2.12.1 Virtual banks
The virtual bank feature is available when the NOR flash is connected to IFC_CS0_N. In
that case, the value of VBANK[0:2] will be driven into three XOR gates, which toggle
the MSB's of the NOR address, as shown in the below figure.

B_IFC
IFC_A[30:8]
IFC_A[7:5]

A[23:25]
Figure 2-13. Virtual bank interface
When VBANK[0:2]=000, the IFC_A[7:5] is not altered, and the NOR flash behaves
normally. If VBANK[0:2]=100, the LB_A[5] is toggled and effectively swaps the top
and bottom halves of the NOR flash. If program "A" was stored in the bottom half and
program "B" in the top half then, while selecting different VBANK settings, “A” and “B”
will get their VBANKs changed as given in the below table.

NOTE
In the above table, the NOR flash has been partitioned into
eight 16 MB zones, which can be arranged under the control of
VBANK.
