The RSA public key for the selected keyslot can be written here. When writing the RSA key, the key is copied to 0x1000B500-RSA_bytesize, length RSA_bytesize. The engine determines the RSA byte-size by checking where the first word of the key was written. Normally the byte-size is 0x100, for RSA-2048.

The RSA signature can be written here, and the data read from here is the message. The message padding must be checked by software. When writing the RSA signature, the signature is copied to 0x1000B900-RSA_bytesize, length RSA_bytesize. The engine determines the RSA byte-size by checking where the first word of the signature was written.
