100 = Disable in Timeslot 2
101 = Disable in Timeslot 1
110 = Controlled by CLKOUT_ENA
111 = Controlled by CLKOUT_ENA
CLKOUT output source select
0 = FLL output
1 = 32.768kHz oscillator
Crystal Start-Up Inhibit
0 = Disabled
1 = Enabled
When XTAL_INH=1, the ‘ON’ transition is inhibited until
the crystal oscillator is valid
Crystal Oscillator Enable
0 = Disabled at all times
1 = Enabled in OFF, ON and SLEEP states
(Note that the BACKUP behaviour is determined by
XTAL_BKUPENA.)
Selects the RTC and 32.768kHz oscillator in BACKUP
state
0 = RTC unclocked in BACKUP
1 = RTC maintained in BACKUP
(Note that XTAL_ENA must also be set if the RTC is to
be maintained in BACKUP.)
FLL Automatic Mode Enable
0 = Manual configuration mode
1 = Automatic configuration mode
(To enable the FLL output, FLL_ENA must also be set
in Automatic mode)
FLL Automatic Mode Frequency select
000 = 2.048MHz
001 = 11.2896MHz
010 = 12MHz
011 = 12.288MHz
100 = 19.2MHz
101 = 22.5792MHz
110 = 24MHz
111 = 24.576MHz
