Interrupt requests are arriving at RST 6.5 pin, at a rate of 200 requests/second. Write a program to
utilize these pulses, to design a real time clock, which will count up to 1 hour. Keep the count of
seconds, minutes and hour in 3 memory locations SECOND, MINUTE and HOUR respectively. Once 1
hour is over, disable the interrupts. Assume interrupting pulses are sufficiently long enough to be
An 8 bit ADC is being used for digitising an analog sensor output. If ADC output pins are connected to
port A of 8255. SOC and EOC pin are connected to PCO and PC7 respectively. WAP to input the sensor
data every minute and store it in memory location EXDATA.
Write a program to display the following "ALL OF US ARE HERE" and rotate it in address and data LEDS. Use 8279 chip.
