NOTES:
11. 14.67MHz requires an odd divisor in the prescaler. Note that both edges of OSC are used to create MCLK and QCLK, thus a deviation from
50% duty cycle in OSC will result in corresponding changes in MBUS timing.
12. Timing delays between OSC and internal clocks are shown for information purposes only.
