O
Program Store Enable: The read strobe for external program memory. When the microcontroller
accesses external program memory, PSEN is driven low in order to enable memory devices. PSEN
is only active when external code accesses are performed.

I
External Access/Wait/Programming Supply Voltage: The EA input determines whether the
internal program memory of the microcontroller is used for code execution. The value on the EA pin
is latched as the external reset input is released and applies during later execution. When latched
as a 0, external program memory is used exclusively, when latched as a 1, internal program
memory will be used up to its limit, and external program memory used above that point. After reset
is released, this pin takes on the function of bus Wait input. If Wait is asserted high during any
external bus access, that cycle will be extended until Wait is released. During EPROM
programming, this pin is also the programming supply voltage input.
