Display RAM address and display mode
STFPC311
Note:
The display RAM stores the data transmitted from an external device to the STFPC311
through the serial interface and is assigned addresses, in units of 8-bits see Table 3.
Only the lower 4 bits of the addresses assigned to Seg17 through Seg20 are valid, the higher
4 bits are ignored.
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 its grid, there is
nothing on the display.
