Either check books in you library or google for it. If the instructor is going to ask about this either he provided a handout or it is your book right ?
AD0 to AD15 is the address bus. AD0 to AD7 is also the data bus.
The address is put on the address bus. The latch is enabled. Then the data is put on the data bus and read by the micro. **broken link removed**
here i have address from AD0 to AD7 connected to the latch circuit and at the same time to the EPROM, so in which one the address will be put.
what i know is the address A0 - A7 is low byte and A8-A15 will be high byte, but why?
how the data will be put on the data bus (do u mean it will be put by the EPROM?
The low byte of the address goes though the latch. The high byte is connected directly as you can see. Port 0 then becomes the data bus and reads the output byte from the EPROM. **broken link removed**
