Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
To operate 8087 in maximum mode, the pin MN/MX (active low) is
A
connected to Vcc or power supply
B
connected to ground
C
left unconnected
D
none of the mentioned
Explanation: 

Detailed explanation-1: -Explanation: The 8087 can operate in a maximum mode, only when the MN/MX (active low) pin of the CPU is grounded. In maximum mode, all the control signals are derived using a sequence chip known as a bus controller.

Detailed explanation-2: -The purpose of the 8087 was to speed up computations for floating-point arithmetic, such as addition, subtraction, multiplication, division, and square root.

Detailed explanation-3: -Released in 1980, the Intel 8087 is the math coprocessor designed to accompany the 16-bit 8086 and 8088 microprocessors. The 8087 fits into a 40-pin dual in-line package (DIP) socket that provides the chip with the same addressing and data handling capabilities as the CPU it matches.
