7.10.7 Flash Error Detection and Correction Sector Disable Register (FEDACSDIS)
This register is used to disable the SECDED function for one or two sectors from the EEPROM Emulation
Flash (bank 7). An additional two sectors can have SECDED disabled by the use of the FEDACSDIS2
register (see
Figure 7-17. Flash Error Detection and Correction Sector Disable Register (FEDACSDIS)

SectorID1_inverse
0-3Fh
The sector ID inverse bits are used with the sector ID bits to determine which sector is
disabled. If the sector ID bits are not pointing to a valid sector (0-3) or the sector ID
inverse bits are not an inverse of the sector ID bits, then no sector is disabled by disable
ID 1.

SectorID1
0-3Fh
The sector ID bits are used with the sector ID inverse bits to determine which sector is
disabled. If the sector ID bits are not pointing to a valid sector (0-3) or the sector ID
inverse bits are not an inverse of the sector ID bits, then no sector is disabled by disable
ID 1.

0-Fh
The sector ID inverse bits are used with the sector ID bits to determine which sector is
disabled. If the sector ID bits are not pointing to a valid sector (0-3) or the sector ID
inverse bits are not an inverse of the sector ID bits, then no sector is disabled by disable
