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 96 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, see the “System Boot,

Fusemap, and eFuse” chapter in the i.MX 7Dual Application Processor Reference Manual (IMX7DRM).

1 Normal operation current consumption includes only the current from the ADC core. It does not include static current from the

power pads.

2 Power-down current includes only the current from the ADC core. It does not include static current from the power pads.

3 IOP and IPD are measurable only on the ADC core's test chips. Because AVDD10 is shared with internal logic power, IOP

and IPD in the test plan only measure current consumption @ AVDD18, VREF.
