At the beginning of the bus cycle the address and chip select are de- coded transparently and qualified with read or write going low. On a read operation, data must not be driven for 5nsec after read goes low to al- low the bus to clear. Once data is driven, data ac- knowledge is driven low to notify the processor that data is on the bus and ready to be read. The processor reads the data and responds by raising read. This is an indication that the processor has compleated the read and cycle is complete. Data acknowledge and data must go to high im- pedence within 20ns to clear the bus for the next L6245 11/15 |
