The System Controller embeds a Boot Sequence Configuration Register (BSC_CR) to save timeout delays on boot. The
boot sequence is programmable through the 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.
