$$A,B,C$$ and $$D$$ are input bits, and $$Y$$ is the output bit in the $$XOR$$ gate circuit of the figure below. Which of the following statements about the sum $$S$$ of $$A,B,C,D$$ and $$Y$$ is correct?

Which one of the following statements regarding the $$INT$$ (interrupt) and the $$BRQ$$ (bus request) pins in a $$CPU$$ is true?

In an $$8085$$ $$A$$ microprocessor based system, it is desired to increment the contents of memory location whose address is available in $$(D,E)$$ register pair and store the result in same location. The sequence of instructions is

The associated figure shows the two types of rotate right instruction $${R_1},\,{R_2}$$ available in a microprocessor where Register is a $$8$$-bit register and $$C$$ is the carry bit. The rotate left instructions $$L1$$ and $$L2$$ are similar except that $$C$$ now links the most significant bit of Register instead of the least significant one.

Suppose Register contains the $$2's$$ complement number $$11010110.$$ If this number is delivered by $$2$$ the answer should be
