Description
This is used to write to the Amiibo app-data stored in memory, when the app-data was already setup for the user application. When the size is <0xD8-bytes, the remaining app-data in memory has data from a "PRNG" written to it.
Besides the usual NFC module state checks, this command can only be used when a certain state u8 field is non-zero, otherwise an error is returned.
