This pin may be either RESET or RESETB. RESETB is active
low. In the case of the AME8520 and AME8530 this pin will
always be the opposite polarity from pin 3. This pin can be
push/pull or open drain.

MRB
Manual Reset. Active low. Pulling this pin low 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 V
DD
.

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 tristate this
pin to disable the watch dog feature.

V
DD
Positive power supply. A reset is asserted after this voltage
drops below a predetermined level. After V
DD
rises above that
level reset remains asserted until the end of the reset timeout
period.
