Boot Mode Configuration
This section provides information on boot mode configuration pins allocation and boot devices interfaces
allocation.
5.1
Boot Mode Configuration Pins
Table 108 provides boot options, functionality, fuse values, and associated pins. Several input pins are also
sampled at reset and can be used to override fuse values, depending on the value of BT_FUSE_SEL fuse.
The boot option pins are in effect when BT_FUSE_SEL fuse is ‘0’ (cleared, which is the case for an
unblown fuse). For detailed boot mode options configured by the boot mode pins, please refer to the
i.MX53 Fuse Map document and Boot chapter in i.MX53 Reference Manual.
