Note 6: Maximum rate of voltage change must be less than 0.5 V/ms.
Note 7: Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at rails and outputs open.
Note 8: The HALT mode will stop CKI from oscillating in the RC and the Crystal configurations. Measurement of IDD HALT is done with device neither sourcing or
sinking current; with L, C, and G0–G5 programmed as low outputs and not driving a load; all outputs programmed low and not driving a load; all inputs tied to V_CC;
clock monitor and comparators disabled. Parameter refers to HALT mode entered via setting bit 7 of the G Port data register. Part will pull up CKI during HALT in crys-
tal clock mode.
Note 9: 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. WARNING: Voltages in excess of 14V will cause damage to the
pins. This warning excludes ESD transients.
Note 10: Parameter characterized but not tested.
