DCO High Speed Divider.
Sets value for high speed divider that takes the DCO output f
000 = 4
001 = 5
010 = 6
011 = 7
100 = Not used.
101 = 9
110 = Not used.
111 = 11
CLKOUT Output Divider.
Sets value for CLKOUT output divider. Allowed values are [1] and [2, 4, 6, ..., 2
odd divider values will be rounded up to the nearest even value. The value for the N1 reg-
ister can be calculated by taking the divider ratio minus one. For example, to divide by 10,
write 0001001 (9 decimal) to the N1 registers.
0000000 = 1
