MB91101/MB91101A
5. PWM Timer
The PWM timer can output high accurate PWM waves efficiently.
The MB91101 and MB91101A have 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 scyde 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 Ï, Ï/4, Ï/16, Ï/64
⢠The counter value can be initialized âFFFFHâ by the resetting or the counter borrow.
