This LSI has two channels of 8-bit PWM timers, A and B (PWMU_A and PWMU_B). Each
PWMU outputs 6 PWM waveforms. Each of the PWM channels of a PWMU can operate
independently. A PWMU allows long-period PWM outputs for six channels in 8-bit single-pulse
mode and for three channels in 16-bit single-pulse mode. In addition, PWM outputs at a high
carrier frequency are available in 8-bit pulse division mode. Connecting a low-pass filter
externally to the LSI allows the PWMU to be used as an 8-bit D/A converter.
