Boot Sequence Configuration Register
The System Controller embeds a Boot Sequence Configuration Register to save timeout delays
on boot. The boot sequence is programmable through the Boot Sequence Configuration Regis-
ter (BSCR).
This register is powered by VDDBU, the modification is saved and applied after the next reset.
The register is taking Factory Value in case of battery removing.
This register is programmable with user programs or SAM-BA and key-protected.
• VDDBU powered
• Product-dependent order
