While firmware verification is a robust security feature, it presents specific challenges in the UIS8141E ecosystem: The following draft explores the technical landscape of

3.2 Functional Verification

• Loopback Tests: Specific registers or output pins are toggled and read back.
• Command Response Test: The host sends a challenge (e.g., GET_FW_VER), and the UIS8141E must respond with a predetermined, correctly formatted reply.
• Timing Analysis: Interrupt latencies and communication timeouts must fall within specified bounds.

Step 2 – Checksum Matching

After downloading, compute the hash:
