Caution The internal high-speed oscillation frequency will increase in speed if the HIOTRM register
value is incremented above a specific value, and will decrease in speed if decremented below
that specific value. A reversal, such that the frequency decreases in speed by incrementing the
value, or increases in speed by decrementing the value, will not occur.
