Note 2: Maximum rate of voltage change must be
Note 3: Supply current is measured after running 2000 cycles with a square wave CKI input, CKO open, inputs at rails and outputs open.
Note 4: The HALT mode will stop CKI from oscillating in the RC and the Crystal configurations. Measurement of I

clock monitor and comparator 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
crystal clock mode.
Note 5: Pins G6 and RESET are designed with a high voltage input network. These pins allow input voltages
biased at voltages
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 6: The output propagation delay is referenced to the end of the instruction cycle where the output change occurs.
Note 7: Parameter characterized but not tested.
