FlexRay Communication Controller (FlexRAY)
NOTE
If the counter has reached its maximum value 0xFFFF and is in the
multicycle mode (SSCCRn[MCY] = 1), the counter is not reset to 0x0000.
The application can reset the counter by clearing the SSCCRn[MCY] bit
and waiting for the next cycle start, when the controller clears the counter.
Subsequently, the counter can be set into the multicycle mode again.
