tC = instruction cycle time.

Note 2: Maximum rate of voltage change must be < 0.5 V/ms.

Note 3: Supply and IDLE currents are measured with CKI driven with a square wave Oscillator, CKO driven 180˚ out of phase with CKI, inputs connected to VCC

and outputs driven low but not connected to a load.

Note 4: The HALT mode will stop CKI from oscillating. Measurement of IDD HALT is done with device neither sourcing nor sinking current; with L. A. B, C, E, F, G0,

and G2–G5 programmed as low outputs and not driving a load; all D outputs programmed low and not driving a load; all inputs tied to VCC; A/D converter and clock

monitor and BOR disabled. Parameter refers to HALT mode entered via setting bit 7 of the G Port data register.

Note 5: Pins G6 and RESET are designed with a high voltage input network. These pins allow input voltages > VCC and the pins will have sink current to VCC when

biased at voltages > VCC (the pins do not have source current when biased at a voltage below VCC). These two pins will not latch up. The voltage at the pins must

be limited to < 14V. WARNING: Voltages in excess of 14V will cause damage to the pins. This warning excludes ESD transients.

Note 6: If timer is in high speed mode, the minimum time is 1 MCLK. If timer is not in high speed mode, the minimum time is 1 tC.

Note 7: Absolute Maximum Ratings should not be exceeded.

Note 8: VCC must be valid and stable before G6 is raised to a high voltage.
