DESCRIPTION:
The ALT_TIMING bit (bit 8) of the PPI_CONTROL register, which allows software to configure which edge the PPI data is sampled on with
respect to the PPI frame sync, is not functional. The bit always reads as 0, and writing a 1 has no effect.
WORKAROUND:
None.
APPLIES TO REVISION(S):
0.3, 0.4
DESCRIPTION:
Fetches at the boundary of either reserved memory or L1 Instruction cache memory (if instruction cache enabled) which is covered by a
valid CPLB cause a false Hardware Error (External Memory Addressing Error).
WORKAROUND:
1) Do not place branch instructions or data at page boundaries. Leave at least 76 bytes free before any boundary with a reserved memory
space. This will prevent false exceptions from occuring.
2) Have the exception handler confirm whether the exception was valid or not before taking action. This can be done by verifying if the
CODE_FAULT_ADDR (or the DATA_FAULT_ADDR) register contains an address that is within a valid page. In that case, no action is
performed.
Note that this anomaly also happens on the boundary of L1_code_cache if instruction cache is enabled.
APPLIES TO REVISION(S):
0.3, 0.4, 0.5, 0.6
