FlexRay Communication Controller (FLEXRAY)
NOTE
If the counter has reached its maximum value 0xFFFF and is in the
multicycle mode, i.e. 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.
