The erratum is limited to the case where two (or more) message buffers are
configured for slot 1 and cycle filtering is used.
Effects:
If a running message buffer scan is interrupted by the NIT it cannot be
guaranteed that the correct message buffer is used for transmission in slot 1 of
the next cycle.
Workaround
If cycle filtering is used, assign all message buffers configured for slot 1 to the
static buffers section. I.e. message buffer number < MRC.FDB[4:0].
FlexRay_AI.086 Bit IBFS of Register CUST1 always 0
Bit IBFS (Input Buffer Status) of register CUST1 (Busy and Input Buffer Control
Register) is always read as 0
to decide which of the two Input Buffer RAMs (IBF) is accessible by the host (via
CIF) as Input Buffer.
Note: It is ensured by hardware that bits IBF1PAG and IBF2PAG (Input Buffer
Workaround
After a write access to change the status of IBF1PAG or IBF2PAG, e.g. the
following sequence may be used to determine which IBF is currently accessible:
1. read register CUST1
2. write the desired value to IBF1PAG or IBF2PAG (must be different from read
3. read register CUST1

value)
1/2 Page Select) of register CUST1 can only be written when the
corresponding IBF is accessible. Otherwise, the value written to IBF1PAG
or IBF2PAG is ignored. Writing 1
correct selection of the upper page of the accessible IBF, writing 0
both bits at the same time leads to a correct selection of the lower page
of the accessible IBF.
