NOTES:
6. HMCLKI = 1 / 2MCLKI
7. Only applies when MCLKI is selected as master source clock.
8. Also applies to MCLKO falling edge when MCLKO = MCLKI/2 or MCLKI/4
9. HMCLKO = 1 / 2MCLKO. MCLKO has the same duty cycle as MCLKI when MCLKO = MCLKI. When MCLKO = 0.5 MCLKI or 0.25
MCLKI, the duty cycle of MCLKO is typically 50%.
10. When MCLKO is derived from MCLKI, MCLKO jitter = MCLKI jitter
