Question

49. Which pin is used for synchronizing the speed of 8085 with slow peripheral devices?
i) RESET
ii) HOLD
iii) READY
IV) INTR​

Answer 1

Answer:

20

The ground is connected to Vss at pin number 20. X0 & X1 are the inputs from the clock generating circuit. It is shown at Pin number 1 & 2 respectively. It is used to synchronize the operations of the 8085 microprocessor.

Answer 2

Answer:

The correct answer is option iii) READY.

Explanation:

• To connect with a slow peripheral device, a CPU uses a ready signal.
• It ensures that the CPU and slow devices are properly synchronised.
• This is a low-energy signal that regulates the microprocessor's write operations.
• The information will be written to the I/O device or memory once the WR pin becomes tiny.
• The READY pin on the 8085 microprocessor is used to check whether a device is ready to accept or send data.
