12.6 System Option 3

The system option 3 parameter value, combines several configuration parameters into one byte, using each bit to represent different parameter options (see the following table). When a programmer is modifying any bit field within this byte-wide memory location, the programmer must perform a read-modify-write type of operation. This prevents accidentally altering bit field values that were not the intended target bit, causing unwanted device behavior changes.
