How to connect peripheral device to 1-byte external expansion memory?

Latest Updated:03/20/2017


How can I connect a peripheral device to perform byte access to a 1-byte external expansion memory?


If access to external expansion memory is fixed to 8 bits, you can connect the device as is.
However, be aware that if 16-bit access occurs, it does not operate correctly.
It is necessary to manage so that instruction fetches and stack operations other than 16-bit access via instructions do not occur in the external expansion memory.
