SCDQ554XX Interface to Siemens/Intel 8031 Microprocessor (using serial port in mode 0)
SCDQ554XX Interface to Siemens/Intel 8031 Microprocessor (using one bit of parallel port as serial input)
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 display 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.
