the Port 0 Error and Status CSR. A 16 byte data payload of the Maintenance Port-write packet contains the contents of

Error Detect CSR, and the Port 0 Error Detect CSR are used to describe the encountered error condition.
7.3 sRIO Errors Supported
7.3.1 Physical Layer Errors
Enable column lists the control bits that may disable the error checking associated with a particular error (if blank, error
checking cannot be disabled). The Cause Field column indicates what cause field will be used with the associated packet-
not-accept control symbol for Input Error Recovery. The EME Error Enable/Detect column indicates which bit of the
P0ERECSR allows the error to increment the Error Rate Counter and lock the Port 0 Error Capture registers, and likewise
which bit of the P0EDCSR is set when the error has been detected.
