Output
If ASYNC in TCB.CTRLB is written to '0' ('1'), the output pin is driven synchronously (asynchronously) to the TCB clock. The bits CCMPINIT, CCMPEN, and CNTMODE in TCB.CTRLB control how the synchronous output is driven. The bits CCMPINIT, CCMPEN, and CNTMODE in TCB.CTRLB control how the synchronous output is driven. The different configurations and their impact on the output is listen in the table below.
