3.3.2.16
Channel A Status Error Counter Register (CASERCR)
This register provides the channel status error counter for channel A. 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 FlexRay module 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 3.4.18, “Slot Status Monitoring
”.
3.3.2.17
Channel B Status Error Counter Register (CBSERCR)
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 FlexRay module 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.
