Hi,

Quick question - I think I know the answer but I thought I'd check.

I have an external flash device connected to the 80c52 with (PSEN ANDed with RD), A0-A13, etc connected.

My question is:
If accessing 2000H upwards - this will access the external flash - what address is actually applied onto A0-A13?

I take it it's 2000H and so 0000H-1FFFH of external flash is inaccessible (unless the address wraps).
