DISTRIBUTION OUTPUT CHARACTERISTICS (OUT0, OUT0 TO OUT13, OUT13)
Duty cycle performance is specified with the invert divider bit set to 1, and the divider phase bits set to 0.5. (For example, for Channel 0,
0x190[7] = 1 and 0x192[7:2] = 1.) Output Voltage Reference VDD in Table 9 refers to the 3.3 VDD3_OUT[x:y] supply.
