FlexRay Module (FLEXRAYV2)
3.3.2.46
Additional Reset: [RUN Command]
Each of these four registers provides the slot status counter value for the previous communication cycle(s)
and is updated at each cycle start. The value depends on the control bits and fields in the related internal
slot status counter condition register, which can be programmed by using the
Condition Register

Slot Status Counter Registers (SSCR0–SSCR3)

If the counter has reached its maximum value 0xFFFF and is in the
multicycle mode, i.e. SSCCRx.MCY = ‘1’, the counter is not reset to
0x0000. The application can reset the counter by clearing the MCY bit and
waiting for the next cycle start, when the FlexRay module clears the counter.
Subsequently, the counter can be set into the multicycle mode again.
