FIFO Data Mode
In this mode the user can set the CCAPnL, CCAPnH, CCAP(n+1)L and CCAP(n+1)H as a buffer chain.
After all these buffers are set, it can change the duty sequentially trigger by T0OF, T1OF, T3OF or S0TOF.
This function is enabled, the CPU can leave it to run by itself to earn more time slot to do other operations. For
example, when the power converter start to raise the voltage from light load to heave load, it might useful to
set the duty larger than the target it the beginning period, and then reduce the duty step by step close to the
target duty. It can just set all duties in the buffer and leave it to finish.

Enhanced PWM Control
The PCA provides the variable PWM mode to enhance the control capability on PWM application. There
are additional 10/12/16 bits PWM can be assigned in each channel and each PWM channel with different
