Note 18:
Rate of voltage change must be less then 0.5 V/ms.
Note 19:
Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at rails and outputs open.
Note 20:
The HALT mode will stop CKI from oscillating in the RC and the Crystal configurations. Test conditions: All inputs tied to V
CC
, L and G ports in the
TRI-STATE mode and tied to ground, all outputs low and tied to ground. The Clock Monitor and the comparators are disabled.

Note 21:
Pins G6 and RESET are designed with a high voltage input network for factory testing. 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 750
(typical). These two pins will not latch up. The voltage at the pins must be limited to less than 14V.
Note 22:
The output propagation delay is referenced to the end of the instruction cycle where the output change occurs.
