Functional Description
SAM9G35
SAM9G35
The PMERRLOC search operation is started as soon as a write access is detected in the ELEN
register and can be disabled by writing to the ELDIS register. The ENINIT field of the ELEN reg-
ister shall be initialized with the number of Galois field elements to test. The set of the roots can
be limited to a valid range.
Table 28-1.
Table 28-2.
When the PMEERRLOC engine is searching for roots the BUSY field of the ELSR remains
asserted. An interrupt is asserted at the end of the computation, and the DONE bit of the ELSIR
register is set. The ERR_CNT field of the ELISR indicates the number of errors. The error posi-
tion can be read in the PMERRLOCx registers.
