SUB M
What is the purpose of the control word written to control register in 8255
Consider the following addresses for PA PB 31H, PC CWR 33H. Write the set of instructions to set PC0 and PC2 using BSR mode.
Give the different types of command words used in 8259.
An Intel 8085 microprocessor is operated at a frequency of 2 MHz. If the instruction STA E 000H is executed, then what is the instruction cycle time? 7x2=14
2. With the help of a neat block diagram, explain the architecture of the 8085 microprocessor. 14
