Microprocessor Interface
The microprocessor interface is through the serial port, SPI port
or one out of eight data bits on the eight bit parallel port and
also control lines SDCLK and LOAD.
Power Up Sequence
Upon power up display will come on at random. Thus the dis-
play should be reset at power-up. The reset will set the
Address Register to Digit 0, User RAM is set to 0 (display blank)
the Control Word is set to 0 (100% brightness with Lamp Test
off) and the internal counters are reset.
Cascading Multiple Displays
Multiple displays can be cascaded using the CLK SEL and CLK
I/O pins as shown below. The display designated as the Master
Clock source should have its CLK SEL pin tied high and the
slaves should have their CLK SEL pins tied low. All CLK I/O pins
should be tied together. One display CLK I/O can drive 15 slave
CLK I/Os. Use RST to synchronize all display counters.
