The data to be written must be signed with a private key, and the signed data must be verified with a public key stored in SEMPER Secure.
 It takes time to verify with ARM M0.
 During verification or in case of verification failure (tampering), only the FF value can be read. If successful, the correct value will be read.
 (The latest programming guide has an explanation, but an NDA may be required for more detailed information.
