  A fascinating matter, since as shown in Figure 8-18 of DS30430C-page
50, the watchdog timer itself is inhibited, but if the MUX selecting the
RESET source from either WDT or pre(post)scaler should glitch and the
latter contain a MSB of 1, this would be seen as reset.

  This is worth looking into, as an alternate and potentially *fast*
(< 1 ms) answer to the FAQ "How do you perform a full hardware reset in
software?"

  One learns something new everyday!
