[1]
Port 1, 2, 3, and 4 enter the bidirectional state (except the I2C pins) with a weak pull-up after reset. In this state, the pins can be used as
inputs or outputs. See the 80C51 Family Hardware Description for details of the port structure.
A reset does not assert the strong pull-up for two clock cycles for these ports which normally occurs when the port transitions from a
LOW to a HIGH state. You must first write a zero, then a logic one to enable the strong pull-up for two clock cycles.
[2]
ALE loading issue: When ALE pin experiences higher loading (>30 pF) during the reset, the microcontroller may accidentally enter into
modes other than normal working mode. The solution is to add a pull-up resistor of 3 k
to 50 k to V
DD, e.g., for ALE pin.
[3]
For 6-clock mode, ALE is emitted at 13 of crystal frequency.

I/O
Address Latch Enable: ALE is the output signal for latching
the low byte of the address during an access to external
memory. This pin is also the programming pulse input (PROG)
for flash programming. Normally the ALE[2] is emitted at a
constant rate of 16 the crystal frequency[3] and can be used for
external timing and clocking. One ALE pulse is skipped during
each access to external data memory. However, if AO is set to
‘1’, ALE is disabled.
