ARTRY Assertion When Using Pipeline Depth of Zero

Date Added: 10/15/2002

Description: Internal (60x) slave maintains a pipeline depth of zero by asserting AACK only af-

ter TA. When ARTRY is asserted the 60x bus access will be terminated and TA will not be as-

serted. Therefore the Internal (60x) slave will not assert AACK since TA was not asserted.

Workaround: Use a pipeline depth of one (BCR[PLDP]=0) for applications that require mem-

ory coherency.

Fix Plan: TBD

SIU19

Bus Monitor Timeout When Using External Slave

Date Added: 10/15/2002

Description: When using an external 60x bus slave with the bus monitor activated, PSDVAL is

not asserted when the external slave is accessed, which could cause the bus monitor to time-out

and TEA to be asserted.

Workaround: The following workarounds

Use pipeline depth of zero (BCR[PLDP]=1) when using an external 60x bus slave.

Disable 60X bus monitor, SYPCR[PBME]=0.

If the external 60x bus slave is another 810x or 826x device, connect the PSDVAL

signals together.

Fix Plan: TDB

Extended Mode on Local Bus

Date Added: 6/13/2000

Description: Using Extended mode on the local bus can generate incorrect transactions in certain

combinations of consecutive reads and writes.

Workaround: Do not use Extended mode on the local bus.

EFC1

Inaccurate EFCOP IIR Outputs for Two or Fewer Coefficients

Date Added: 8/15/2000

Description: When using normal (dual) DMA or flyby DMA transfers which have a maximum

transfer size greater than 32 bits with the EFCOP to perform IIR filtering with two or less IIR co-

efficients, the first output of the IIR filter is lost. The rest of the outputs are shifted and inaccurate.

Workaround: Use only DMA 32-bit maximum transfer size for both input and output channels.

Device Withstands ESD CDM Stress of 400 V Instead of 500 V

Date Added: 10/31/2002

Description: Device meets the ESD specifications for Human Body Model (HBM) of 1000 V

and Machine Model (MM) of 100 V but does not withstand the Charged Device Model (CDM)

of 500 V. All pins are guaranteed to withstand CDM of 400 V.

Workaround: NA

Fix Plan: TBD
