tC = instruction cycle time.

Note 9: Maximum rate of voltage change must be < 0.5 V/ms.

Note 10: 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 11: 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 12: 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 < (VCC +7V. WARNING: Voltages in excess of 14V will cause damage to the pins. This warning excludes ESD transients.

Note 13: 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 14: Absolute Maximum Ratings should not be exceeded.

Note 15: Vcc must be valid and stable before G6 is raised to a high voltage.
