Names and Functions
Address Latch Enable:
Output pulse for latching the low byte of the address during an
access to external memory. In normal operation, ALE is emitted
twice every machine cycle, and can be used for external timing or
clocking. Note that one ALE pulse is skipped during each access to
external data memory. Setting SFR SCONF.0 can disable ALE. With
this bit set, ALE will be active only during a MOVX instruction.
#PSEN

32
Program Store Enable:
The read strobe to external program memory. When executing code
from the external program memory, #PSEN is activated twice each
machine cycle, except that two #PSEN activations are skipped
during each access to external data memory. #PSEN is not activated
during fetches from internal program memory.
#EA

External Access Enable
:
#EA must be externally held low to enable the device to fetch code
from external program memory locations. If #EA is held high, the
device executes from internal program memory.

Crystal 1
:
Input to the inverting oscillator amplifier and input to the internal
clock generator circuits.
