2.2 Recommendation on ALE
For application that require no external memory or
temporarily no external memory: the ALE output signal
(pulses at a frequency of 1⁄6 fOSC) can be disabled under
software control (bit 5 in PCON SFR: ‘RFI’); if disabled, no
ALE pulse will occur. ALE pin will be pulled down
internally, switching an external address latch to a quiet
state. The MOVX instruction will still toggle ALE as a
normal MOVX.
ALE will retain its normal HIGH value during Idle mode and
a LOW value during Power-down mode while in the ‘RFI
reduction mode’.
Additionally during internal access (EA = 1) ALE will toggle
normally when the address exceeds the internal Program
Memory size. During external access (EA = 0) ALE will
always toggle normally, whether the flag ‘RFI’ is set or not.
