NAME AND FUNCTION
TYPE
PIN
NO.
PSEN
32
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.
EA/WAIT/
V
PP
35
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.
XTAL1

I
Crystal 1:
Input to the inverting amplifier used in the oscillator circuit and input to the internal clock
generator circuits.
XTAL2

O
Crystal 2:
Output from the oscillator amplifier.
