PCP_TC.036 Unexpected behaviour after failed posted FPI write
If PCP posts an FPI write (including those in atomic FPI operations) which
produces an FPI error, following malfunctions may be observed:
•
•
•
•
•
•
Workaround
In a product intent system, FPI errors are extremely unlikely and no workaround
is required. For debugging purposes, it may be useful to prevent these issues
by not allowing any pending FPI write (PCP_FTD.FPWC = 10
action may impact PCP performance. Register PCP_FTD
3F30
Note: FPI errors are extremely unlikely and, in any case, are an indication of
PCP_TC.038 PCP atomic PRAM operations may operate incorrectly
PCP atomic PRAM instructions (XCH.PI, MSET.PI, MCLR.PI) may operate
incorrectly due to external FPI read-modify-write operations.
Workaround
If atomicity is required for the application, replace all atomic PRAM instructions
with FPI RMW instructions (XCH.F, SET.F, CLR.F).

The PCP may lock the FPI bus
Improper PCP instruction execution may occur
PRAM content corruption
A subsequent COPY operation could write incorrect data
A subsequent invalid BCOPY (i.e. a BCOPY instruction which will also
generate an FPI error) could cause the next channel to perform an
unexpected error exit
A byte or half-word COPY in the next channel may write incorrect data
symbolic name may therefore not be supported by all versions of tools (compiler,
debugger, etc.).
