Input Signals
Description
Output Signals
Description
GRESET
Reset generated by the
WatchDog Timer,
Voltage Comparator or
Reset pin input.
WDOG_EN
A product term that
enables the WatchDog
Timer. An active high
pulse of minimum 20ns
duration.
or
ERESET
ERESET is the output
of the Pulse Generator
that is triggered by
GRESET.
GRESET or ERESET
is an active low signal.
WDOG_ON
Active high WatchDog
output. Will remain
active until the
WatchDog is cleared
by WDOG_CLR.
WDOG_CLR
A product term that
clears and re-loads
the WatchDog Timer.
An active high pulse
of minimum 20ns
duration.
GPLD Inputs
Other GPLD inputs,
refer to the GPLD
chapter.
SUPERV_CLK
The clock generated
by the Supervisory
Function. If the
WatchDog Timer runs
on the internal oscillator,
SUPERV_CLK is
connected to the 2KHz
oscillator. Otherwise
SUPERV_CLK is
connected to the external
CLKIN/8192.
