This option bit determines if a reset is generated when entering Halt mode while the
Watchdog is active.
0: No reset generation when entering Halt mode
1: Reset generation when entering Halt mode
0: 32-kHz oscillator (VLP) selected as AWU clock
1: AWU RC oscillator selected as AWU clock.
When the internal RC oscillator is not selected (CKSEL1=1), these option bits (and
CKSEL0) select the range of the resonator oscillator current source or the external
clock source.
These option bits indicate the size of sector 0 according to
