The memory data path read capture low register, shown in

data path during error capture.

The memory data path read capture ECC register, shown in

were on the data bus when an error was detected.

The memory error detect register stores the detection bits for multiple memory errors, single- and

multiple-bit ECC errors, and memory select errors. It is a read/write register. A bit can be cleared by

writing a one to the bit. System software can determine the type of memory error by examining the

contents of this register. If an error is disabled with ERR_DISABLE, the corresponding error is never

detected or captured in ERR_DETECT.
