256-kbyte extended area
∆ When CS256E = 0, used as
basic extended area.
When WAIT pin function is not
selected while CS256E = 1,
CS256 is output and address
pins A17 to A0 are used.

CP extended area
∆ When RAME = 0, used as
basic extended area.
∆ When CPCSE = 0, used as
basic extended area.

When CPCSE = 1, CPCS1 is
output in the CP extended area
and address pins A12 to A0 are
used.
