Freescale Semiconductor 97
3.3.2.24 Slot Counter Channel A Register (SLTCTAR)
This register provides the number of the current slot in the current communication cycle for channel A.
3.3.2.25 Slot Counter Channel B Register (SLTCTBR)
This register provides the number of the current slot in the current communication cycle for channel B.
3.3.2.26 Rate Correction Value Register (RTCORVR)
This register provides the sign extended rate correction value in microticks as it was calculated by the clock
synchronization algorithm. The FlexRay module updates this register during the NIT of each odd
numbered communication cycle.
