Loading Serial Character Data
Table „Character ’D’“ (page 8) shows the Row Address for the
example character “D.” Column data is written and read asynchro-
nously from the 140 bit RAM. Once loaded the internal oscillator
and character multiplexer reads the data from the RAM. These
characters are row strobed with column data as shown in Figures
„Row and Columns Locations for a Character ’D’“ (page 8) and
„Row Strobing“ (page 9). The character strobe rate is determined
by the internal or user supplied external MUX Clock, the IC’s
counter and the prescaler.
