Functional Description
The display's user interface is organized into five memory areas.
They are accessed using the Flash Input, FL, and address lines,
A3 and A4. All the listed RAMs and Registers may be read or writ-
ten through the data bus. See Table Memory Selection“
(page 10). Each input pin is described in Pin Definitions.
RST can be used to initialize display operation upon power up or
during normal operation. When activated, RST will clear the Flash
RAM and Control Word Register (00H) and reset the internal
counter. All eight display memory locations will be set to 20H to
show blanks in all digits.
FL pin enables access to the Flash RAM. The Flash RAM will set
(D0=1) or reset (D0=0) flashing of the character addressed by A0–
A2.
The 1 x 8 bit Control Word Register is loaded with attribute data if
A3=0.
The Control Word Logic decodes attribute data for proper imple-
mentation.
Character ROM is designed for 128 ASCII characters. The ROM
is Mask Programmable for custom fonts.
The Clock Source could either be the internal oscillator
(CLKSEL=1) of the device or an external clock (CLKSEL=0) could
be an input from another IPD213X display for synchronizing blink-
ing for multiple displays.
The Display Multiplexer controls the Row Drivers so no additional
logic is required for a display system.
The Display has eight digits. Each digit has 35 LEDs.
