(1) All IDD measurements taken with suitable decoupling capacitors across the power supply to suppress the
transient switching currents inherent in CMOS designs (see Section 2.2.1).
(2) Typical values are at mid point of voltage range and at 25°C only.
(3) RUN and WAIT IDD: measured using an external square-wave clock source (fOSC = 4.2 MHz); all inputs
0.2V from rail; no DC loads; maximum load on outputs 50pF (except OSC2 load 20pF).
WAIT IDD: only the timer system active; current varies linearly with the OSC2 capacitance.
WAIT and STOP IDD: all ports configured as inputs; VIL = 0.2V and VIH = VDD – 0.2V.
STOP IDD: measured with OSC1 = VDD.
