Modulate error data from digital filter circuit
(Initial value)
1
Modulate data written in data register
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 pin.
However, it is possible to output only drum phase filter results from CAPPWM pin,
by DFUCR settings of the digital filter circuit.
See the section 26.11, Digital Filters, explaining the digital filter computation circuit.
