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 VCC;
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 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 750
(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.
