Function
Ready Input. When the ready function is
enabled, a high level at this pin during an
external memory access will force the
insertion of memory cycle time waitstates until
the pin returns to an low level.
External Access Enable pin. A low level at this
pin during and after Reset forces the CPU to
begin instruction execution out of external
memory.
Note: This pin must always be set to ’0’.
