FlexRay Communication Controller (FLEXRAY)
This register provides the channel status error counter for channel B. The protocol engine generates a slot
status vector for each static slot, each dynamic slot, the symbol window, and the NIT. The slot status vector
contains the four protocol related error indicator bits vSS!SyntaxError, vSS!ContentError, vSS!BViolation,
and vSS!TxConflict. The controller increments the status error counter by 1 if, for a slot or segment, at least
one error indicator bit is set to 1. The counter wraps around after it has reached the maximum value. For
more information on slot status monitoring see Section 22.6.18, Slot Status Monitoring.
