Hi All,
According to datasheet(revF), setting XMxPAR[15] allows byte write capability without using BHE and BLE for two 8 bit memory sharing the same memory region.
Now, I have following question about this behavior.
When set XMxPAR as 0xF0FF and write data to two 8bit external memories,
Thanks for your help.
Regards,

Hi Mike-san,
After I read the diagram, I had a only one question.
In your diagram, the address input pins of external memory are connected to ADDR[0:14].
I think these should be connected to ADDR[1:15] because ADDR[0] will be incremented by 1 when ADuC7026 writes data to external memories each other, then if ADDR[0] is connected to address input pin, the half of address space in external memories cannot be used.
Do you agree with me?
Best Regards,
