Field
Description
0–31 Error Address. This read-only field is the reference address from slave port n that generated the
EADDR access error.
30.6.3 MPU Error Detail Register, Slave Port n (MPU_EDRn)
When the MPU detects an access error on slave port n, 32 bits of error detail are captured in this read-only
register and the corresponding bit in the MPU_CESR[SPERR] field set. Information on the faulting
address is captured in the corresponding MPU_EARn register at the same time. Note this register and the
corresponding MPU_EARn register contain the most recent access error; there are no hardware interlocks
with the MPU_CESR[SPERR] field as the error registers are always loaded upon the occurrence of each
protection violation.
