DESCRIPTION
Up to 4 pages of display data can be stored in internal memory. An on-chip ROM memory contains the character sets. The STV5342 performs automatic selection of one of up to six natural languages. Data bytes may be decoded in either 7-Bit plus parity or in full 8-Bit formats. The chip set also supports facilities for reception and display of higher-level protocol data.
