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
Read-Out Protection, when selected provides a protection against program memory
content extraction and against write access to Flash memory. Erasing the option bytes
when the FMP_R option is selected will cause the whole memory to be erased first,
and the device can be reprogrammed. Refer to
Flash Programming Reference Manual for more details.
