The second type of reset in SAA-XC886 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.
