Row Strobing
Multiplexer and Display Driver
The four characters are row multiplexed with RAM resident column
data. The strobe rate is established by the internal or external
MUX Clock rate. The MUX Clock frequency is divided by a 448
counter chain. This results in a typical strobe rate of 768 Hz. By
pulling the Clock SEL line low, the display can be operated from an
external MUX Clock. The external clock is attached to the CLK I/O
connection (pin 8). The maximum external MUX Clock frequency
should be limited to 3 MHz.
When a high speed external clock is used the frequency can be
further divided down by 16 by using the built in prescaler. In the
control word format data bit D4 is set high (D4=1). It is not recom-
mended to use the prescaler with the internal clock.
An asynchronous hardware Reset (pin 6) is also provided. Bring-
ing this pin low will clear the Character Address Register, Control
Word Register, RAM, and blanks the display. This action leaves the
display set at Character Address 0, and the Brightness Level set at
100%.
The user can activate four Control functions. These include: LED
Brightness Level, IC Power Down, Prescaler, or Display Clear.
OPCODEs and six bit words are used to initiate these functions.
The OPCODEs and Control Words for the Character Address and
Loading Column Data are shown in Tables Load Character
Address“ (page 10) and Load Column Data“ (page 10).
