4) When error is detected
the error log latches the
error status of the local,
global, system registers
and the error information
associated with the error.
FERR logs the first error
detected and NERR logs
the next error. This
example shows a
datapath uncorrectable
ECC error detected.
1) Each IIO internal error can be
configured as one of the 3
severities of error. This example
configures the uncorrectable
ECC error as severity 1 error for
IIO
2) The global error status
indicates which interface has
reported an error.
3) Error detected is
converted to a system event
according to how the error
severity is mapped to a
system event. In this
example CPEI is generated
for error severity
