Parameters are valid over operating temperature range unless otherwise specified.
Load capacitance for port 0, ALE, and PSEN = 100 pF, load capacitance for all other outputs = 80 pF.
Interfacing the microcontroller to devices with float times up to 45 ns is permitted. This limited bus contention will not cause damage to
Port 0 drivers.
Parts are tested down to 2 MHz, but are guaranteed to operate down to 0 Hz.
