4.3.2 Frame Format
Figure 4-13 illustrates the ISO/IEC14443 TypeB frame format. SOF(Start Of Frame) and EOF(End Of Frame)
are added to a data field. The maximum size of data field is 256 bytes in this RFID.

Additionally, the ISO/IEC14443-4 block format shown in Figure 4-14 is applied to the data field shown in
Figure 4-13. This RFID does not support CID and NAD of the first field, so adding them is prohibited.
