T16a2 interrupts
The T16A2 module can generate the following six kinds of interrupts:
• Compare A interrupt (in comparator mode)
• Compare B interrupt (in comparator mode)
• Capture A interrupt (in capture mode)
• Capture B interrupt (in capture mode)
• Capture A overwrite interrupt (in capture mode)
• Capture B overwrite interrupt (in capture mode)
Each timer channel outputs a single interrupt signal shared by the above interrupt causes to the interrupt controller
(ITC). Read the interrupt flags in the T16A2 module to identify the interrupt cause that has been occurred.
