Chapter 4 RF Communication Mode
4.3.8.5 Address
In ISO/IEC14443 TypeB (command is compliant with ISO/IEC7816-4), the addresses of READ and WRITE
commands are specified by bytes P1 and P2 of the command APDU. (See Section 4.3.5 Upper Command
Format)
Figure 4-25 shows the address specification format. Set bit 7 of byte P1 to 0; setting to 1 causes an error.
