DIAGNOSTIC (D430)
The fault correction memory diagnostic performs the following functions:
•
Verifies the Fault Logging Interface (FLI) PCA array and reads the previous history of both arrays
(when present) and lists all errors.
•
Clears and verifies both Memory Control and Logging (MCL) PCA arrays.
•
Verifies all Semiconductor Memory Array (SMA) PCA arrays and lists any errors.
•
Checks the capability to detect and correct single bit errors in both data and check bits, detects
most multi-bit errors, and detects I/O failures in the Fault Correction Array (FCA) PCA.
•
Executes the main diagnostic program for all SMA PCA's.
•
Reads and lists the error history of both MCL logging arrays.
The following procedure is used to verify operation:
