Note 11: tC = Instruction cycle time (Clock input frequency divided by 10).

Note 12: Maximum rate of voltage change must be < 0.5 V/ms.

Note 13: 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 14: The HALT mode will stop CKI from oscillating in the R/C and the Crystal configurations. In the R/C configuration, CKI is forced high internally. In the crystal

or external configuration, CKI is TRI-STATE. Measurement of IDD HALT is done with device neither sourcing nor sinking current; with L. F, C, G0, and G2–G5 pro-

grammed as low outputs and not driving a load; all outputs programmed low and not driving a load; all inputs tied to VCC; clock monitor disabled. Parameter refers

to HALT mode entered via setting bit 7 of the G Port data register.

Note 15: 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). The effective resistance to VCC is 750Ω (typical). 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 16: The output propagation delay is referenced to the end of the instruction cycle where the output change occurs.

Note 17: Parameter characterized but not tested.

Note 18: Rise times faster than this specification may reset the device if POR is enabled and may affect the value of Idle Timer T0 if POR is not enabled.
