This bit only enables the crystal oscillator. Its selection as system clock must be done man-
ually.
0 = Crystal oscillator is enabled during reset, resulting in longer reset timing
1 = Crystal oscillator is disabled during reset, resulting in shorter reset timing

Reserved—Altering this register may result in incorrect device operation.
Programming the XTLDIS bit to zero on 8-pin versions of this device prevents any fur-
ther communication via the debug pin. This is due to the fact that the XIN and DBG
functions are shared on pin 2 of this package. Do not program this bit to zero on 8-pin
devices unless no further debugging or Flash programming is required.
