ST25TA64K
RF command sets
42
The FSDI field codes the FSD that defines the maximum size that an RF host is able to
receive. Table 46 gives the conversion from FDSI to FSD.
The DID field defines the value of the addressed ST25TA64K.
The FSCI codes the FSC which stands for the maximum frame size that the ST25TA64K is
able to receive. The ST25TA64K is able to receive up to 256 bytes of command. If the RF
host sends a command with more than 256 bytes, the ST25TA64K will not be able to treat
the command and will not reply.
The FWI which stands for the Frame Waiting time Integer codes the FWT. This time
corresponds to the maximum duration while an RF host shall send before sending the next
command.
