9.4.1.25
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.
