The display RAM bitmap shows the direct relationship between the display RAM column and the
segment outputs, between the bits in a RAM row and the backplane outputs, and between the
RAM rows and banks.

Input and output banks can be set independently from one another with the bank-select
commands (see Section 8.7.2 on page 22). Figure 35 shows the concept.
