Display memory mapping
The mapping between the eight segment registers and the segment outputs S1 to S32 is given in Tables 1 and 2.
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).
Table 1
Segment byte-segment driver mapping in direct drive mode
Mapping example: bit 0 of register 7 controls the LCD segment S25 if BANK bit is a logic 1.
Table 2
Segment byte-segment driver mapping in duplex mode
Note
1.
Where X = don’t care.
Mapping example: bit 7 of register 5 controls the LCD segment S24/BP2.
