PSEN is not activated during fetches from internal program memory. ALE/PROG 53 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 the oscillator frequency and can be used for external timing or clocking. It should be noted 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 Auxiliary0. With this bit set ALE will be active only during a MOVX instruction. EA/VPP 54 External Access Enable/Programming Supply Voltage: EA must be externally held LOW to enable the device to fetch code from external program memory locations starting with 0000H. If EA is held HIGH the device executes from internal program memory unless the program counter contains an address greater than 3FFFH (16 kbytes boundary). This pin also receives the 12.75 V programming supply voltage (VPP) during EPROM programming. If security bit 1 is programmed EA will be internally latched on reset.
