The P-Flash word addressed by ECCRIX = 001 contains the lower 16 bits of the global address. The
following four words addressed by ECCRIX = 010 to 101 contain the 64-bit wide data phrase. The four
data words and the parity byte are the uncorrected data read from the P-Flash block.
The D-Flash word addressed by ECCRIX = 001 contains the lower 16 bits of the global address. The
uncorrected 16-bit data word is addressed by ECCRIX = 010.
18.3.2.15 Flash Option Register (FOPT)
The FOPT register is the Flash option register.
All bits in the FOPT register are readable but are not writable.

ECC Parity Bits — Contains the 8 parity bits from the 72 bit wide P-Flash data word or the 6 parity bits,
allocated to PAR[5:0], from the 22 bit wide D-Flash word with PAR[7:6]=00.
Global Address — The GADDR[22:16] field contains the upper seven bits of the global address having
caused the error.
