Question

Explain the function of the following pin of 8085 Micro-processor:

READY

Answer 1

1. The microprocessor uses an input signal to determine if a peripheral is ready to send data.
2. This signal pauses the CPU until a slow-responding peripheral is ready to send or receive data.
3. A high READY value indicates that the peripheral is ready. If it is low, the CPU waits for an integral number of clock cycles before going high.
4. It is used to synchronize slower devices with faster microprocessors.
