When an error is detected by one of the above sources, both the Error Source and Error Code number will
be logged into the Error Log FIFO. The Error Source is a 6-bit field indicating the location of the error. The
Error Code is an 8-bit field, and designates the type of error that occurred. The Error Management Block
provides a single Error Log and arbitrates between error sources for access to the Error Log. The Error
Management Block records the errors up to the speed of arbitration between all of the sources.
The device provides an Error Log Read Register which allows the user to read out the first error from the
Error Log. This is a 32-bit register which lists the location and type of error (Error Source, Error Code: 14
bits) that occurred. When this register is read, the device returns the first entry in the Error Log.
The device provides the user with the ability to reset the contents of Error Log FIFO and the Error Log Read
Register.
