FlexRay Module (FLEXRAYV2)
3.3.2.28
This register provides the sign extended offset correction value in microticks as it was calculated by the
clock synchronization algorithm. The FlexRay module updates this register during the NIT.

Rate Correction Value — protocol related variable:
correction)
This field provides the sign extended rate correction value in microticks as it was calculated by the clock
synchronization algorithm. The value is represented in 2’s complement format. This value does not include the
value limitation and the application of the external rate correction. If the magnitude of the internally calculated
rate correction value exceeds the limit given by rate_correction_out in the

Note: If the FlexRay module was not able to calculate a new rate correction term due to a lack of synchronization
