There is one set of 16-bit registers in the error detection circuitry that stores the
computed CRC signature. A non-zero value on the syndrome register causes the
CRC_ERROR pin to be set high.

Error Detection
State Machine
This register contains the CRC signature of the current frame through the error detection
verification cycle. The CRC_ERROR signal is derived from the contents of this register.
This 46-bit register contains information on the error type, location of the error, and the actual
syndrome. The types of errors and location reported are single- and double-adjacent bit errors.
The location bits for other types of errors are not identified by the error message register. The
content of the register is shifted out through the JTAG SHIFT_EDERROR_REG instruction or to
the core through the core interface.
