While RST is high, PSEN and the port pins are pulled high; ALE The reset input is the RST pin. To reset, hold the RST pin high is pulled low. All SFRs are reset to their reset values as shown for a minimum of 24 oscillator periods while the oscillator is in table 3. The internal Data Memory content is indeterminate. running.

A memory access occurs immediately after the RST line is brought low, but the data is not brought into the processor. The memory access repeats on the next machine cycle and actual processing begins at that time. 5
