#6150 - 80c562 rom/ram address decode
Hardware question on 80c562:
. program memory from 0h to 7fffh and ram memory 8000h to ffffh.
. any reason that a15 and its complement can not be used to decode the ram and rom memory space - as in the standard 8051 schematics ?

thnks for your response ! avron bryan
