26.8.30 CLK_FLL_CONFIG
Description:
FLL Configuration Register
Address:
0x40261530
Offset:
0x1530
Retention:
Retained
IsDeepSleep:
Yes
Comment:
This register contains frequency lock loop (FLL) configuration. FLL circuit settings should not
be changed while it is a selected clock (connected to logic). This prevents clock glitches that
can crash the logic. Deselect the FLL using .BYPASS_SEL=FLL_REF
Default:
0x1000000

Description
0:17 FLL_MULT RW R 0 Multiplier to determine CCO frequency in multiples of
the frequency of the selected reference clock (Fref).
Ffll = (FLL_MULT) * (Fref / REFERENCE_DIV) /
(OUTPUT_DIV+1)
24 FLL_OUTPUT_DIV RW R 1 Control bits for Output divider. Set the divide value
before enabling the FLL, and do not change it while
FLL is enabled.
0: no division
1: divide by 2
