In the NDEF file choice state, physical address 0x000C of Block0 the NDEF file top, the top (physical address
0x0010) becomes address 0x0002 of the NDEF file.) of Block1. In other words, the NLEN field of the NDEF
file is placed in 0x000C - 0x000D of the physical address, and the NDEF message field is placed by 0x0010 of
the physical address.
