Notes:
(1) All values shown reflect average measurements.
(2) Typical values at midpoint of voltage range, 25°C only.
(3) Wait IDD: Only timer system active.
(4) Wait, Stop IDD: All ports configured as inputs, VIL=0.2Vdc, VIH=VDD–0.2Vdc.
(5) Run (operating) IDD, Wait IDD: Measured using external square wave clock source to OSC1 (fOSC=2.0MHz), all inputs 0.2Vdc
from rail; no DC loads, less than 50pF on all outputs, CL=20pF on OSC2.
(6) Stop IDD measured with OSC1=VSS.
(7) Wait IDD is affected linearly by the OSC2 capacitance.
