4.3.5 Upper Command Format
The upper commands (SELECT, READ, WRITE) are compliant with the APDU (Application Protocol Data
Unit) format of ISO/IEC7816-4.
Figure 4-18 shows the command APDU format. Table 4-16 shows the command APDU field definition. Figure
4-19 gives the response APDU format. Table 4-17 gives the response APDU field definition.
The command APDU format shown in Figure 4-18 and the response APDU format shown in Figure 4-19 are
configured in the information field INF of the ISO/IEC14443-4 block format shown in Figure 4-14.
