Note:
Display RAM address and display mode
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
Only the lower 4 bits of the addresses assigned to Seg
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.
