Manual Reset input for a Reset switch.
This input allows a push button switch to be directly con-
nected to the MCP131X/2X MR pin, which can then be
used to force a system Reset. This input filters (ignores)
noise pulses that occur on the MR pin.
L = Switch is depressed (shorted to ground). This forces
H = Switch is open (internal pull-up resistor pulls signal

Watchdog Timer Input
The WDT period is specified at the time of device order.
The Standard WDT period is 1.6s typical.
An edge transition on the WDI pin resets the Watchdog
Timer counter (no time out). A Falling Edge is required to
start the WDT Timer.
