Pin descriptions
2.1
MR
A logic low on MR asserts the reset output. Reset remains asserted as long as MR is low
and for trec after MR returns high. This active-low input has an internal pull-up. It can be
driven from a TTL or CMOS logic line, or shorted to ground with a switch. Leave open if
unused.
2.2
WDI
If WDI remains high or low for 1.6 s, the internal watchdog timer runs out and reset
(or WDO) is triggered. The internal watchdog timer clears while reset is asserted or when
WDI sees a rising or falling edge.
The watchdog function can be disabled by allowing the WDI pin to float.
2.3
WDO
It goes low when a transition does not occur on WDI within 1.6 s, and remains low until
a transition occurs on WDI (indicating the watchdog interrupt has been serviced). WDO also
goes low when VCC falls below the reset threshold; however, unlike the reset output, WDO
goes high as soon as VCC exceeds the reset threshold. Output type is push-pull.
Note:
For those devices with a WDO output, a watchdog timeout will not trigger reset unless WDO
is connected to MR.
2.4
RST
Pulses low when triggered, and stays low whenever VCC is below the reset threshold or
when MR is a logic low. It remains low for trec after either VCC rises above the reset
threshold, or MR goes from low to high.
2.5
RST
Goes high with triggered, and stays high whenever VCC is above the reset threshold or
when MR is a logic high. It stays high for trec after either VCC falls below the reset threshold,
or MR goes from high to low.
2.6
PFI
When PFI is less than VPFI, PFO goes low; otherwise, PFO remains high. Connect to
ground if unused.
