Figure 8. Loading Serial Character Data
Table 1 shows the Row Address for the example character
“D.” Column data is written and read asynchronously 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 9 and 10.
The character strobe rate is determined by the internal or user
supplied external MUX Clock, the IC’s counter and the pres-
caler.
