7.7 Display memory mapping

The mapping between the eight segment registers and the segment outputs S1 to S32 is

given in Table 5 and Table 6.

Since only one register bit per segment is needed in the direct drive mode, the BANK bit

allows swapping of display information. If BANK is set to logic 0, even bytes (BANK A) are

displayed; if BANK is set to logic 1 odd bytes (BANK B) are displayed. BP1 is always used

for the backplane output in the direct drive mode. In duplex mode, even bytes (BANK A)

correspond to backplane 1 (BP1) and odd bytes (BANK B) correspond to backplane 2

(BP2).
