The POR bit WDCON.6 is set only by the power on reset. The WTRF bit WDCON.2 is set when the
Watchdog timer causes a reset. A power on reset will also clear this bit. The EWT bit WDCON.1 is
cleared by power on resets. This disables the Watchdog timer resets. A watchdog or external reset does
not affect the EWT bit.
