Note: When PWMs output data from the digital filter circuit, the data consisting of the speed and phase
filtering results are modulated by PWMs and output from the CAPPWM and DRMPWM pins.
However, it is possible to output only drum phase filter results from CAPPWM pin and only capstan
phase filter result from DRMPWM pin, by DFUCR settings of the digital filter circuit.
See the section explaining the digital filter computation circuit.
