| This is the [[CTCert]] issuer type: 0 = retail "Nintendo CA - G3_NintendoCTR2prod", non-zero = dev "Nintendo CA - G3_NintendoCTR2dev".
| This determines if the OTP is for a dev system; it indicates the [[CTCert]] issuer type: 0 = retail "Nintendo CA - G3_NintendoCTR2prod", non-zero = dev "Nintendo CA - G3_NintendoCTR2dev".

| Manufacturing date (of the SoC?). Usually month(s) before the dates in the logs stored in [[Flash_Filesystem|TWLNAND]]. Each byte is one field: year, month, day, hour, minute, second. Year is encoded as year-1900 so that it fits in one byte.

| This is the CTCert ECDSA exponent, this is byte-swapped when plaintext_otp+0x18 is >=5.
| This is the CTCert expiry time as UNIX timestamp, this is specified in big endian if the OTP version is <5.
