| Last 3-bytes here are used with the following HMAC where the size is 0x1DF-bytes. The u16 starting at byte1 is used for the first two bytes in the 0x40-byte input buffer for Amiibo [[Process_Services_PXI|crypto]] init. The first byte must be 0xA5. The remaining bytes are initially(before the Amiibo is written to) all-zero. Byte[2](maybe big-endian u16 starting at byte1?) here is incremented each time the Amiibo is written to.
