Note 13:
All parameters apply to both commercial and industrial temperature operation unless otherwise noted. The value tMCS is a function of
the machine cycle clock in terms of the processor’s input clock frequency. These relationships are described in the Stretch Value
Timing
table. All signals characterized with load capacitance of 80pF except Port 0, ALE,
PSEN, RD, and WR with 100pF. Interfacing
to memory devices with float times (turn off times) over 25ns can cause bus contention. This does not damage the parts, but causes
an increase in operating current. Specifications assume a 50% duty cycle for the oscillator. Port 2 and ALE timing changes in relation
to duty cycle variation. Some AC timing characteristic drawings contain references to the CLK signal. This waveform is provided to
assist in determining the relative occurrence of events and cannot be used to determine the timing of signals relative to the external
clock.
