MB90246A Series
4. 8-bit PWM Timer
The 8-bit PWM timer is a re-load timer module that can generate a pulse wave with any period/duty ratio. It uses
pulse output control according to timer operation for PWM (Pulse Width Modulation) output.
An appropriate external circuit allows the 8-bit PWM timer to operate as a D/A converter.
The 8-bit PWM timer module consists of two 8-bit re-load registers used to specify “H” width and “L” width and
of a down counter that is loaded alternately with those values and counts down.
A pulse waveform with any period and duty ratio is generated.
An output pulse’s duty ratio of 0.4 to 99.6 percent can be set.
An appropriate external circuit allows this PWM timer to operate as a D/A converter.
An interrupt request can be generated by counter underflow.
The count clock can be selected from two types of timebase timer output.
