Note 8: Pins G6 and RESET are designed with a high voltage input network. These pins allow input voltages greater than V_CC and the pins will have sink current
to V_CC when biased at voltages greater than V_CC (the pins do not have source current when biased at a voltage below V_CC). The effective resistance to V_CC 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.
