7.4 Mapping between Memory Columns and Segments
The mapping relation between the column outputs of the Display Data Memory and the Segment outputs SEG0~SEG63
is decided by the CSM (Column/Segment Mapping) input.
If CSM input is connected to HIGH, then data from column 0 of the Display Data Memory is output from SEG0. This type
of mapping is called normal mapping.
If CSM input is connected to LOW, then the data from column 63 of the Display Data Memory is output from SEG0. This
type of mapping is called inverted mapping.
By use of this input, the flexibility of component placement and routing on a PCB can be increased.
