Notes
a.
The algebraic convention whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
b.
Typical values are for DESIGN AID ONLY, not guaranteed or subject to production testing.
c.
WDI is internally serviced within the watchdog period if WDI is left unconnected.
