DWMBB Adapter
3.14.10 Error Conditions in Diagnostic Modes
When diagnostics are being performed, error conditions, such as parity
errors, ECC errors, and illegal DMA address errors, cause the DWMBB to
fail.
While the DWMBB is in BIIC or DMA loopback modes, the DWMBB
handles forced and unforced errors the same as in normal mode. The
error, failing command, and address information, if appropriate, are
logged, and the appropriate error response is taken, if enabled.
Errors that occur in DWMBB/A module loopback mode do not cause the
DWMBB/B module to generate interrupts because the link between the
DWMBB/A module and DWMBB/B module is disabled. However, errors,
failing address, and failing command information are logged and the
interrupt status information is available with Interrupt Sent (ADG1<1>)
even though no interrupt is issued.
