Description
r unused
r PLL lock status:
0 = PLL not locked
1 = PLL locked
r PLL calibration status
0 = Calibration on-going
1 = Calibration performed
Note: Reset to 0 in sleep mode irrespective of
calibration state.
r PLL Calibration Result
0 = Calibration procedure failed
1= Calibration procedure successful
Note: Reset to 0 in sleep mode irrespective of
calibration state
w Triggers PLL calibration, always read as 0.
rw PLL division ratio
00 = Automatic
Others, PLL divider = PLL_divr
r unused
rw VCO band first calibration value
r unused
rw VCO band second calibration value
r unused
rw VCO band third calibration value
r unused
rw VCO band fourth calibration value
r unused
rw _{Enables RC oscillator. RC oscillator is also}
automatically switched on in E²PROM mode.
0 = RC oscillator off
1 = RC oscillator on
rw _{Selects CLKOUT source:}
000 = f_XOSC (32 MHz)
001 = f_XOSC / 2 (16 MHz)
010 = f_XOSC / 4 (8 MHz)
011 = f_XOSC / 8 (4 MHz)
100 = f_XOSC / 16 (2 MHz)
101 = f_XOSC / 32 (1 MHz) (d)
110 = RC clock (65 kHz)
111 = Clock output off.
Note: Switching from RC to f_XOSC or vice versa
can generate glitches
