Q. Microprocessor 8088 has

View solution

Q. Assertion (A): In 8085, P flag is for parity checking.

Reason (R): If the result of ALU has even parity, P flag is set and if the result has odd parity, P flag is reset.

Q. Consider the following statements

1. The sign of a floating point number depends on the sign of mantissa only.
2. If the absolute value of a number is less than 1, the sign of exponent is zero or positive.
3. With sign bit of mantissa as 0, increasing the exponent from a positive to a more positive value gives a larger floating point number.

Which of the above are correct?

Q. Assertion (A): In microprocessor 8085 instruction LXIB, 90 FF H means register B and C are loaded with upper and lower bytes to get B = 90 H and C = FFH.

Reason (R): In 8085 the stack pointer indicates which memory location is to accessed.
