The second type of reset in XC886/888 is the hardware reset. This reset function can be
used during normal operation or when the chip is in power-down mode. A reset input pin
RESET is provided for the hardware reset.
The Watchdog Timer (WDT) module is also capable of resetting the device if it detects
a malfunction in the system.
Another type of reset that needs to be detected is a reset while the device is in
power-down mode (wake-up reset). While the contents of the static RAM are undefined
after a power-on reset, they are well defined after a wake-up reset from power-down
mode.
