Pulse Width Modulation Controller (PWM)
• Each channel is user-configurable and contains:
• Two global registers that act on all three TC Channels
• 4 channels, one 16-bit counter per channel
• Common clock generator, providing Thirteen Different Clocks
• Independent channel programming
• Synchronous Channel mode
• Connection to one PDC channel
• Two independent event lines which can send up to 8 triggers on ADC within a period
• Four programmable Fault Inputs providing asynchronous protection of outputs
