Bit 1 = WDG SW Hardware or software watchdog
Bit 0 = WDG HALT Watchdog Reset on Halt
Option byte 0
OPT 7 = AWUCK Auto-wakeup clock selection
If this bit is reset, OSCRANGE[2:0] must be set to 100.
OPT6:4 = OSCRANGE[2:0] Oscillator range

order to select the 256 clock cycle delay (see
This option bit selects the watchdog type.
0: Hardware (watchdog always enabled)
1: Software (watchdog to be enabled by software)
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
