2. I3C

• Compliant with:
  • MIPI Alliance Specification for I3C Basic, Version 1.1.1
  • MIPI Alliance Specification for I3C HCI, Version 1.2
  • MIPI Alliance Specification for I3C TCRI, Version 1.0
• Operational in both Active and Secondary Controller Modes
• Caliptra subsystem uses only target/secondary controller mode
• OCP Recovery Support

3. Life Cycle Controller (LCC)

• Spec-documented LC states and transitions
• Multiple test unlock tokens for supply chain protection
• Physical presence detection capability for RMA

4. Fuse Controller (FC)

• Caliptra core fuse map spec to Jan 10, 2025
• Production Debug Unlock Support
• Multi-test unlock token support
• Manufacturing time generic secret fuses for SoC usage

5. Manufacturer Control Unit (MCU):

• A dedicated VeeR instance for SoC-specific firmware
• PmP & User Mode Enabled

6. Manufacturer Control Interface (MCI):
