PCP_TC.023 JUMP sometimes takes an extra cycle
Following a taken JUMP, the main state machine may misleadingly take an
additional cycle of pause. This occurs if the already prefetched next or second
next instruction after the JUMP is one of the following instructions:
•
•
•
•
This does not cause any different program flow or incorrect result, it just adds
an extra dead cycle.
Workaround
None.
PCP_TC.027 Longer delay when clearing R7.IEN before atomic PRAM in-
structions
User Manual states that, when clearing R7.IEN, a delay of one instruction
before the mask becomes effective is needed. However, two instructions (for
example, two NOPs) are required between the clearing instruction and an
atomic PRAM instruction (MSET.PI/MCLR.PI/XCH.PI).
PCP_TC.032 Incorrect PCP behaviour following FPI timeouts (as a slave)
When PRAM is being accessed from the FPI bus and an FPI time-out occurs
then this can lead to corruption or loss of the current and subsequent FPI
accesses. In general an FPI time-out during an access to the PCP is unlikely
since FPI time-out is usually programmed for a large number of FPI clock cycles
and the only time that the FPI access cannot be immediately responded to by
the PCP is during the execution of atomic PRAM instructions. FPI accesses are
locked out for the entire duration of any sequence of back to back atomic PRAM
instructions. The combination of a low FPI time-out setting and long sequences
of atomic PRAM instructions could therefore result in FPI time-out.
