## Description

Pulse Width Modulator  
Features  
• Work as one PWM or one timer.  
• 16 bits main counter.  
• PWM/Timer can choose between Wishbone interface clock or external clock as working clock.  
• PWM can choose between dedicated duty cycle input or internal register as source of duty cycle.  
• Duty cycle and period can be changed at runtime.  
• Hosted through Wishbone slave interface.  
• Working clock's frequency can be divided to at most 1/65535 of original frequency.  
• Period register also serves as timer target register when module is in timer mode.
