Command Port Errors
When an error occurs on the command port the appropriate DMAx_GCSR error bit is set. The DMA
channel registers are not updated with command packet data.
Each PowerSpan II external port has error log registers that provides additional diagnostic
information to assist in error recovery. These error log registers indicate when multiple errors
occur due to the pipelined nature of DMA channel requests.
See “Error Handling” on page 157 and “Interrupt Handling” on page 145 for a full description of error
logging support and associated interrupt mapping options.
