bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set ‘0’ = Bit is cleared
bit 7 Unimplemented: Read as ‘0’
bit 6-0 TUN<6:0>: Frequency Tuning bits
1000000 = Minimum frequency

1111111 =
0000000 = Oscillator module is running at the factory-calibrated frequency.

0111110 =
0111111 = Maximum frequency
Note 1: When active clock tuning is enabled (ACTSEL = 1) the oscillator is tuned automatically, the user cannot
write to OSCTUNE.
2: Oscillator is tuned monotonically.
