Display Clear
Data stored in the Character RAM, Control Register, and
Attribute RAM will be cleared if the clear (CLR) is held
low for a minimum of 10 μs. Note that the display will be
cleared regardless of the state of the chip enables (CE

00hex is loaded into all Attribute RAM/Control Register
memory locations.
Data Entry
Figure 2 shows a truth table for the HDLX-2416 display.
Setting the chip enables (CE
cursor select (CU) to logic 1 will enable ASCII data
loading. When cursor select (CU) is set to logic 0, data
will be loaded into the Control Register and Attribute
RAM. Address inputs A
location in the display. Data inputs D
information into the display. Data will be latched into
the display on the rising edge of the WR signal. D

Control
Cursor
When cursor enable (CUE) is a logic 1, a cursor will be
displayed in all digit locations where a logic 1 has been
stored in the Digit Cursor memory in the Attribute RAM.
The cursor consists of all 35 dots ON at half brightness.
A flashing cursor can be displayed by pulsing CUE. When
CUE is a logic 0, the ASCII data stored in the Character
RAM will be displayed regardless of the Digit Cursor bits.
Blanking
Blanking of the display is controlled through the BL input,
the Control Register and Attribute RAM. The user can
achieve a variety of functions by using these controls
in different combinations, such as full hardware display
blank, software blank, blanking of individual characters,
and synchronized flashing of individual characters or
entire display (by strobing the blank input). All of these
blanking modes affect only the output drivers, main-
taining the contents and write capability of the internal
RAMs and Control Register, so that normal loading of
RAMs and Control Register can take place even with the
display blanked.
