Table 27 defines the R-APDU of the System File Select command.

5.6.7

ReadBinary command

On receiving the ReadBinary command, the ST25TA64K reads the requested memory field

and sends back its value in the R-APDU response.

Before sending a ReadBinary command, a file shall be selected by using a Select

command.

The Response of the ReadBinary command is successful when the data to be read is within

the selected file (a); in other words, when the sum of P1-P2 and Le fields is equal to or lower

than the selected file length.

Table 28 defines the ReadBinary command.

Table 29 defines the R-APDU of the ReadBinary command.
