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 s. Note that the
display will be cleared
regardless of the state of the
chip enables (CE
the display is cleared, the ASCII
code for a space (20hex) is
loaded into all character RAM
locations and 00hex is loaded
into all Attribute RAM/Control
Register memory locations.
Data Entry
Figure 2 shows a truth table for
the HDLX-3416 display. Setting
the chip enables (CE
logic 0 and the cursor select
(CU) to logic 1 will enable ASCII
data loading. When cursor select
(CU) is set to logic 0, data will be
0 = Logic 0; 1 = Logic 1; X = Do Not Care

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 con-
trolled 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 syn-
chronized flashing of individual
characters or entire display (by
