RST
I
Reset: A high logic state on this pin for two machine cycles, while the oscillator is running, will
reset the device. If the PSEN# pin is driven by a high-to-low input transition while the RST
input pin is held high, the device will enter the external host mode. Otherwise, the device will
enter the normal operation mode.
EA#
I
External Access Enable: EA#2 must be connected to VIL in order to enable the device to
fetch code from External Program Memory. EA# must be strapped to VIH for internal program
execution. However, security lock level 4 will disable EA#, and program execution is only pos-
sible from internal program memory. The EA# pin can tolerate a high voltage3 of 12V (see
Electrical Specification, Section 12.0).
ALE/
PROG#4
I/O
Address Latch Enable: ALE is the output signal for latching the low byte of the address dur-
ing an access to external memory. This pin is also the programming pulse input (PROG#) for
flash programming. Normally the ALE5 is emitted at a constant rate of 1/6 the crystal fre-
quency and can be used for external timing and clocking. One ALE pulse is skipped during
each access to external data memory.

1. I = Input; O = Output
2. EA# is not sampled and latched on reset after level 2 or level 3 locked. MCU will jump to run internal code if EA# changes from VIL to
VIH. This is a security compromise. Use level 4 lock to fix.
3. It is not necessary to receive a 12V programming supply voltage during flash programming.
4. Applying 10-50 K
pull-up resistor to this pin may improve the device’s performance.
5. ALE loading issue: When ALE pin experiences higher loading (>30pf) during the reset, the MCU may accidentally enter into modes
other than normal working mode. The solution is to add a pull-up resistor of 3-50 K
to VDD, e.g. for ALE pin.
