Note 12: Maximum rate of voltage change must be
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 V
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 I
programmed as low outputs and not driving a load; all outputs programmed low and not driving a load; all inputs tied to V
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
biased at voltages
pins will not latch up. The voltage at the pins must be limited to
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.
