TRIM_OSC 7:0
Type
rw
Description
Oscillator trimming (bit0=LSB; bit7=MSB);
(only writable if TRIM_EN = ‘11’)
Note: TRIM_OSC[0:4] represent the 32-steps fine trimming range with a monotonous behavior from slower to
faster frequency. The step width is ~0.25MHz.
TRIM_OSC[5:7] are modifying the oscillator temperature coefficient. It is strongly recommended to not
change these values.
Due to CDR functionality, it is not required to change these values.
SWK_OPT_CTRL
Selective Wake Options Register (Address 011 1001_B)

Reserved, always reads as 0
Oscillator trimming (bit8=LSB; bit12=MSB);
(only writable if TRIM_EN = ‘11’)
Note: The bit RX_WK_SEL is used to select the respective receiver during Selective Wake operation. To reduce
the quiescent current during Frame Detect Mode it is recommended to select the Low-Power Receiver, i.e.
RX_WK_SEL = ‘1’
Note: TRIM_OSC[8:12] represent the 32-steps coarse trimming range, which is not monotonous.
It is not recommended to change these values.
