VBO Trim Definition
The on-chip Flash only guarantee Write operation with voltage supply over 2.7 V, Write
operation below 2.7 V will get unpredictable results.

DivBy4—Output frequency selection
0 = Output frequency is input frequency
1 = Output frequency is 1/4 of the input frequency
Reserved—Must be 1
{DlyCtl3, DlyCtl2, DlyCtl1}—3 bit selection for the pulse width that can be filtered. See
Table 86
Reserved—Must be 1
{FilterSel1, FilterSel0}—2 bit selection for the clock filter mode
00 = No filter
