SCDQ Block Diagram
The following explains how to format the serial data to be loaded into the display. The user supplies a string of bit mapped decoded char-
acters. The contents of this string is shown in Figure Loading Serial Character Data A“ (page 8). Figure Loading Serial Character
Data B“ (page 8) shows that each character consists of six 8 bit words. The first word encodes the display character location and the suc-
ceeding five bytes are row data. The row data represents the status (On, Off) of individual column LEDs. Figure Loading Serial Character
Data C“ (page 8) shows that each 8 bit word is formatted to include a three bit Operational Code (OPCODE) defined by bits D7–D5 and
five bits (D4–D0) representing Column Data, Character Address, or Control Word Data.
Figure Loading Serial Character Data D“ (page 8) shows the sequence for loading the bytes of data. Bringing the LOAD line low enables
the serial register to accept data. The shift action occurs on the low to high transition of the serial data clock (SDCLK). The least significant
bit (D0) is loaded first. After eight clock pulses the LOAD line is brought high. With this transition the OPCODE is decoded. The decoded
OPCODE directs D4–D0 to be latched in the Character Address register, stored in the RAM as Column data, or latched in the Control
Word register. The control IC requires a minimum 600 ns delay between successive byte loads.
