31.3.12.4 Simple Parity Error

When Dynamic ECC is active and the read is from an address where Flash ECC Control bits CTL selects simple parity, a parity error causes the same behavior as an ECC DED. The error is reported in-band (if ECCCTL[1:0]= 2’b01) and the INTFLAG.DERR bit is set. Unlike a DED, a Bus Error exception is not returned to the initiator.
