The OTP is a read-only memory area which contains various keys and signatures used to decrypt, encrypt or verify various pieces of storage. Its size depends on the console, it is 128 bytes on the Wii and 1024 bytes on the Wii U (split into eight 128 bytes banks). It can be used directly by writing into one register and reading from the other one, without any additional synchronisation. [...]
