Manual Reset
The manual reset input (MR) allows the user to trigger a
reset by using a push-button switch. The MR input is an
active-low debounced input. By connecting a push-button
directly from MR to ground, the designer adds manual
system reset capability (see Figure 4). Reset is asserted if
the MR pin is pulled low to less than 100mV for 1 μ s or longer
while the push-button is closed. After MR is released, the
reset outputs remain asserted for t POR (200ms) and then
released.

Watchdog Timer
The Watchdog Timer circuit checks microprocessor activity
by monitoring the WDI input pin. The microprocessor must
periodically toggle the WDI pin within t WDT (1.6s nominal),
otherwise the reset signal is asserted (see Figure 5).
Internally, the 1.6s timer is cleared by either a reset or by
toggling the WDI input.
Besides the 1.6s default timeout during normal operation,
these devices also have a longer 51s timeout for start-up.
During this time, a reset cannot be asserted due to the WDI
not being toggled. The longer delay at power-on allows an
operating system to boot, an FPGA to initialize, or the
system software to initialize without the burden of dealing
