Combining the 5-bit PWM together with the 3-bit BRM, the average duty
cycle at the output will be (M+N/8)/32, where M is the content of the 5-bit
PWM portion, and N is the content of the 3-bit BRM portion. Using this
mechanism, a true 8-bit resolution PWM type DAC with reasonably high
repetition rate can be obtained.
The value of each PWM data register is continuously compared with the
content of an internal counter to determine the state of each PWM
channel output pin. Double buffering is not used in this PWM design.
