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 V
and outputs driven low but not connected to a load.
Note 4: The HALT mode will stop CKI from oscillating. Measurement of I
H and L programmed as low outputs and not driving a load; all inputs tied to V
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
biased at voltages

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 t
Note 7: Absolute Maximum Ratings should not be exceeded.
