Boot Mode Configuration
4.9
The PLL supplies VDD_DIG_PLL and VDD_ANA_PLL can be powered ON from internal LDO voltage
regulator (default case). In this case VDD_REG is used as internal regulator’s power source. The
regulator’s output can be used as a supply for other domains such as VDDA and VDDAL1.

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.MX53xD Fuse Map document and Boot Chapter in i.MX53xD Reference Manual.
