17.4.7 Buffered 10/12/16-bit PWM Mode

To use 10/12/16-bit PWM mode might cause unexpected duty cycle when change the duty cycle setting
by writing data into CCAPnH and CCAPnL, because the 8 bit CPU can only write one byte at a time. To finish
fully setting it will take two write cycles, and the comparator will output unexpected duty cycle when the first
byte have been written. If the applications need accurate control when change the duty cycle, it needs to use
the Buffered PWM mode.
