Note 9:
Rate of voltage change must be less then 0.5 V/ms.
Note 10:
Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at rails and outputs open.
Note 11:
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 G0–G5 configured as
outputs and set high. The D port set to zero. The clock monitor is disabled.

Note 12:
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 13:
The output propagation delay is referenced to the end of the instruction cycle where the output change occurs.
