(Reset)
Active High
MR
This pin is active low. Pulling this pin low to forces a reset. After a low to high transition reset remains
asserted for exactly one reset timeout period. This pin is internally pulled high. If this function is unused
then float this pin or tie it to Vdd.
WDI
Watch Dog Input. Any transition on this pin will reset the Watch Dog timer. If this pin remains high or
low for longer than the Watch Dog interval then a reset is asserted. Float or tri-state this pin to disable
the Watch Dog feature.
Vdd
Positive power supply. A reset is asserted after this voltage drops below a predetermined level. After
Vdd rises above that level reset remains asserted until the end of the reset timeout period.
