FLL Clock source
00 = MCLK
01 = BCLK
10 = LRC
11 = Reserved
FLL Clock Reference Divider
00 = MCLK / 1
01 = MCLK / 2
10 = MCLK / 4
11 = MCLK / 8
MCLK (or other input reference) must be divided down
to <=13.5MHz.
For lower power operation, the reference clock can be
divided down further if desired.
Frequency of the FLL control block
000 = FVCO / 1 (Recommended value)
001 = FVCO / 2
010 = FVCO / 3
011 = FVCO / 4
100 = FVCO / 5
101 = FVCO / 6
110 = FVCO / 7
111 = FVCO / 8
Recommended that this register is not changed from
default.
FOUT clock divider
000 = 2
001 = 4
010 = 8
011 = 16
100 = 32
101 = 64
110 = 128
111 = 256
(FOUT = FVCO / FLL_OUTDIV)
F
000 = divide by 1
001 = divide by 2
010 = divide by 4
011 = divide by 8
1XX = divide by 16
