    O (I)
    Address Latch Enable/Program Pulse: Output pulse for latching the low byte of the
    address during an access to external memory. In normal operation, ALE is emitted at a
    constant rate of 1/6 (1/3 in X2 mode) the oscillator frequency, and can be used for
    external timing or clocking. Note that one ALE pulse is skipped during each access to
    external data memory. This pin is also the program pulse input (PROG) during EPROM
    programming. ALE can be disabled by setting SFR’s AUXR.0 bit. With this bit set, ALE
    will be inactive during internal fetches.
    PSEN

    O
    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.

    I
    External Access Enable/Programming Supply Voltage: EA must be externally held
    low to enable the device to fetch code from external program memory locations 0000H
    and 3FFFH (54X2) or 7FFFH (58X2). If EA is held high, the device executes from
    internal program memory unless the program counter contains an address greater
    than 3FFFH (54X2) or 7FFFH (58X2). This pin also receives the 12.75V programming
    supply voltage (VPP) during EPROM programming. If security level 1 is programmed,
    EA will be internally latched on Reset.
