Note 8: Pins G6 and RESET are designed with a high voltage input network. These pins allow input voltages greater than VCC and the pins will have sink current
to VCC when biased at voltages greater than VCC (the pins do not have source current when biased at a voltage below VCC). The effective resistance to VCC is 750Ω
(typical). These two pins will not latch up. The voltage at the pins must be limited to less than 14V.
Note 9: Condition and parameter valid only for part in HALT mode.
Note 10: Parameter characterized but not tested.

Note 11: For device testing purposes of all AC parameters, VOH will be tested at 0.5*VCC.
Note 12: The output propagation delay is referenced to the end of the instruction cycle where the output change occurs.
Note 13: Parameter not tested.
Note 14: tc = Instruction Cycle Time.
