Note 2: tC = Instruction cycle time (Clock input frequency divided by 10).
Note 3: Maximum rate of voltage change must be < 0.5 V/ms.
Note 4: 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 5: 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
programmed as low outputs and not driving a load; all outputs programmed low and not driving a load; all inputs tied to VCC; WATCHDOG and clock monitor
disabled. Parameter refers to HALT mode entered via setting bit 7 of the G Port data register.
Note 6: 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 750 (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 7: The output propagation delay is referenced to the end of the instruction cycle where the output change occurs.
Note 8: Parameter characterized but not tested.
Note 9: 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.
