Attributes are non-destructive. If a character with bit D7 set is
replaced by a cursor (Control Word bit D4 is set, and D3=D2=0)
the character will remain in memory and can be revealed again by
clearing D4 in the Control Word.
Blink (D5): The entire display can be caused to blink at a rate of
approximately 2.0 Hz by setting bit D5 in the Control Word. This blink-
ing is independent of the state of D7 in all character locations.
To synchronize the blink rate in a bank of these devices, it is nec-
essary to tie all devices' clocks and resets together as described in
a later section of this data sheet.

Lamp Test (D6): When the Lamp Test bit is set, all dots in the
entire display are lit at half brightness. When this bit is cleared, the
display returns to the characters that were showing before the
lamp test.
Clear Data (D7): When D7 is set (D7=1) in the Control Word, all (dis-
play) memory bits are reset to zero and the display goes blank.
A second control word must be written into the chip with D7 reset
(D7=0) to set up attributes and brightness levels.
The SMC- 4740 oscillator is designed to drive up to 16 displays
with input loading of 15 pF each.
The general requirements for cascading 16 displays are:
1.Determine the correct address for each display.
2.Tie CE0 to ground and use CE1 from an address.
3.Select one of the displays to provide the clock for the
4.Tie CLKSEL to ground on other displays.
5.Use RST to synchronize the blinking between the displays.
