4.4.1 Description

The System Controller embeds a Boot Sequence Controller (BSC). The boot sequence is programmable through the Boot Sequence Controller Configuration register (BSC_CR).

The BSC_CR is powered by VDDBU. Any modification of the register value is stored and applied after the next reset. The register defaults to the factory value in case of battery removal.

The BSC_CR is programmable with user programs or SAM-BA and is key-protected.
