ISO-DEP Protocol13.1.2 SoDThe SoD contains the mandatory PCB and, optionally, the DID.• PCBThe Protocol Control Byte (PCB) is used to convey the information required to control thedata transmission. The protocol defines three fundamental types of blocks:• I-block used to convey information for use by the application layer.• R-block used to convey positive or negative acknowledgements. An R-block nevercontains an INF field. The acknowledgement relates to the last received block.• S-block used to exchange control information between the Reader/Writer and the CardEmulator. Two different types of S-blocks are defined:• Waiting Time eXtension (WTX) containing a 1 byte long INF field• DESELECT containing no INF field.The format of the PCB depends on its type. The format of I-blocks, R-blocks, and S-blocks isshown in Table 80, Table 81, and Table 82.Table 80: Format of I-block PCBb8 b7 b6 b5 b4 b3 b2 b1 Meaning0 0 I-block0 RFUxxChaining, if bit is set to 1bDID following, if bit is set to 1b0 NAD following.

The two mostsignificant bits—b8 and b7—code the power level indicator. The format of the DID field isshown in Table 83.
