Microprocessor The maximum number of seven segment displays that can be connected to 8279 is 8 12 16 18 8 12 16 18 ANSWER DOWNLOAD EXAMIANS APP
Microprocessor Assertion(A): Segment override prefix (SOP) is used when a default offset register is not used with its default base segment register but with a different base register. Reason(R): The offset registers IP and SP can never be associated with any other segment registers apart from their respective default segments. A is false but R is true. Both A & R are true and R is the correct explanation of A. A is true but R is false. Both A & R are true but R is not the correct explanation of A. A is false but R is true. Both A & R are true and R is the correct explanation of A. A is true but R is false. Both A & R are true but R is not the correct explanation of A. ANSWER DOWNLOAD EXAMIANS APP

Microprocessor The reason for the presence of ALE pin in 8085, but not in 6800 is that 8085 has multiplexed bus, whereas 6800 does not have None 8085 has 5 interrupts lines, whereas 6800 has only two 8085 uses I/O mapped I/O, whereas 6800 uses memory mapped I/O 8085 has multiplexed bus, whereas 6800 does not have None 8085 has 5 interrupts lines, whereas 6800 has only two 8085 uses I/O mapped I/O, whereas 6800 uses memory mapped I/O ANSWER DOWNLOAD EXAMIANS APP
