: 1 = External crystal oscillator disable.
: Crystal oscillator warm-up status.
[0,0] = F
[1,0] = F
: Watchdog timer reset enable
F
It represents if the crystal clock is stable(1) or not(0).
0 = External crystal will restart (Default).
Cleared by H/W if XTOFF is set or if PD is set and
WDT is not enabled.
Set by H/W after crystal stabilization time.
0 = Internal RING oscillator disable.
Don’t clear RINGON bit when XTRG = 0.
