Loading Data
Setting the chip enable (CE1, CE2, CE3, CE4) to their true state will
enable loading. The desired data code (D0-D6) and digit address (A0,
A1) must be held stable during the write cycle for storing new data.

Data entry may be asynchronous and random. Digit 0
is defined as right hand digit with A1=A2=0.
To clear the entire internal four-digit memory hold the
clear (CLR) low for 1
μ
s. All illuminated dots will be
turned off within one complete display multiplex cycle,
1 msec minimum. The clear function will clear both the
ASCII RAM and the cursor RAM.
Loading Cursor
Setting the chip enables (CE1, CE2, CE3, CE4) and
cursor select (CU) to their true state will enable cursor
loading. A write (WR) pulse will now store or remove a
cursor into the digit location addressed by A0, A1, as
defined in data entry. A cursor will be stored if D0=1
and will removed if D0=0. The cursor (CU) pulse width
should not be less than the write (WR) pulse or errone-
ous data may appear in the display.
If the cursor is not required, the cursor enable signal
(CUE) may be tied low to disable the cursor function.
For a flashing cursor, simply pulse CUE. If the cursor
has been loaded to any or all positions in the display,
then CUE will control whether the cursor(s) or the
characters will appear. CUE does not affect the con-
tents of cursor memory.
