The second type of reset in XC866 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. To ensure the recognition of the hardware
reset, pin RESET must be held low for at least 100 ns.
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.
