clocked except those which get their clock supply from another clock generator (such
as an external or auxiliary oscillator like the AWU oscillator).
The compatibility of Watchdog operation with AWUFH mode is configured by the
WDGHALT option bit in the option byte. Depending on this setting, the HALT instruction
when executed while the Watchdog system is enabled, can generate a Watchdog
RESET.
