Timing Characteristics—Write Cycle Waveforms
Loading Data
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. Digit 0 is defined as right hand
digit with A1=A2=0.
Clearing the entire internal four-digit memory can be accomplished
by holding the clear (CLR) low for 1.0 msec minimum. The clear
function will clear the ASCII RAM. Loading an illegal data code will
display a blank.
