WATCHDOG TIMER
Note 1:
Reset is guaranteed valid from the selected reset threshold voltage down to the minimum V
CC
.
Note 2:
VDS = V
CC
, WDI unconnected.
Note 3:
Precision timing currents of 500nA are present at both the SRT and SWT pins. Timing capacitors connected to these nodes
must have low leakage consistent with these currents to prevent timing errors.
Note 4:
The sink/source is supplied through a resistor, and is proportional to V
CC
(Figure 8). At V
CC
= 2V, it is typically ±24μA.
