The Character Address bits, D4–D0 stored in the Character
Address Register and the Column Data Instruction’s Row Address
bits, D7–D5, direct the Column Data bits, D4–D0 to specific RAM
location. See the Instruction Set Table for address and data format.
Figure „Writing Character ’D’ Example“ (page 9) shows the Row
Address for the example character “D” See Figure „Character
Address, Row, & Column Data Map“ (page 7) for the dot
positioning (Display contacts are at the top of the display).

Column data is written and read asynchronously from the 200 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 Figure „Row Strobe Example“
(page 10). The character strobe rate is determined by the internal
IC’s÷320 counter.
