Microprocessor Assertion(A): Ready signal of microprocessor is used to detect whether a peripheral is ready for the data transfer or not. Reason(R): In the microprocessor during data transfer operations, the wait states are added by forcing the ready signal low. A is true but R is false. Both A & R are true and R is the correct explanation of A. Both A & R are true but R is not the correct explanation of A . A is false but R is true. A is true but R is false. Both A & R are true and R is the correct explanation of A. Both A & R are true but R is not the correct explanation of A . A is false but R is true. ANSWER DOWNLOAD EXAMIANS APP
