Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 15-6 Unimplemented: Read as ‘0’
bit 5-0 TUN<5:0>: FRC Oscillator Tuning bits

000001
000000 = Center frequency, oscillator is running at factory calibrated frequency

100000 = Minimum frequency deviation
Note 1: Increments or decrements of TUN<5:0> may not change the FRC frequency in equal steps over the FRC
tuning range and may not be monotonic.
