TUNSEL
The bullet points in the second paragraph of
Section 2.6.3 “OSCTUN2 Register” on page 24
are modified. The modified values indicate that the
OSCTUNE register does not affect the INTRC
frequency. The modified values are indicated in
bold text in the following excerpt of the section:
R/W-0
TUNSEL: INTRC Frequency bit
1 = INTRC frequency adjusted according to the values of the OSCTUN2<5:1> bits
0 = INTRC not affected
Unimplemented: Read as ‘0’
TUN<5:1>: Frequency Tuning bits – Adjusts the frequency of INTRC when TUNSEL is set
011111 = Maximum frequency
•
•
000001
000000 = Center frequency. Oscillator module is running at the calibrated frequency
111111
•
•
100000 = Minimum frequency
TUN<0>: Placeholder. This bit has no effect on the INTRC frequency.
