Pulse Width Modulation Controller (PWM)
SAM3S Summary
• Each channel is user-configurable and contains:
• Two global registers that act on all three TC Channels
• Quadrature decoder
• 2-bit Gray Up/Down Counter for Stepper Motor
• One Four-channel 16-bit PWM Controller, 16-bit counter per channel
• Common clock generator, providing Thirteen Different Clocks
• Independent channel programming
• Synchronous Channel mode
• Connection to one PDC channel
• independent event lines which can send up to 4 triggers on ADC within a period
