PWM Timer
The PWM timer can output high accurate PWM waves efficiently.
MB91121 series has inner 4-channel PWM timers, and has the following features.
Each channel consists of a 16-bit down counter, a 16-bit data resister with a buffer for cycle setting, a 16-bit
compare resister with a buffer for duty setting, and a pin controller.
The count clock of a 16-bit down counter can be selected from the following four inner clocks.
Inner clock
φ, φ/4, φ/16, φ/64
The counter value can be initialized “FFFFH” by the resetting or the counter borrow.
