Request from the application to reset the user watchdog
timer with its initial count. A falling edge of this signal
triggers a reset of the user watchdog timer.
When driven low, this signal triggers the device to
reconfigure. If requested by the factory configuration, the
application configuration specified in the remote update
control register is loaded. If requested by the application
configuration, the factory configuration is loaded.
Clocks the remote configuration shift register so that the
contents of the status and control registers can be read
out, and the contents of update register can be loaded.
The shift register latches data on the rising edge of the
