Unimplemented: Read as ‘0’
TUN<5:1>: Frequency Tuning bits – Adjusts the frequency of INTOSC. Can adjust INTRC, depending
on TUNSEL (OSCTUN2<7>)
011111 = Maximum frequency

000001
000000 = Center frequency. Oscillator module is running at the calibrated frequency
111111
•
•
100000 = Minimum frequency
TUN<0>: This bit is a placeholder and has no effect on the INTOSC frequency.
