Normal display memory locations

Only the lower 4 bits of the addresses assigned to Seg17 through Seg20 are valid, the higher

4 bits are ignored.

Note that the common grid/segment outputs are grid-based. The grid has to be enabled

before any segments can be turned on. If data is written for a segment before enabling the

respective grid, nothing is present on the display.
