Table 24. ATR Codes for Higher Density Atmel CryptoMemory
Once the asynchronous mode has been selected, it is not possible to switch to the synchronous mode without
powering off the device.
Figure 8. Power Up Sequence for Smart Card Mode
After a successful ATR, the Protocol and Parameter Selection (PPS) protocol defined by ISO 7816-3 may be used to
negotiate the communications speed with Atmel
CryptoMemory supports D values of 1, 2, 4, 8, 12 and 16 for an F value of 372. CryptoMemory also supports D values
of 8 and 16 for F = 512. This allows selection of 8 communications speeds ranging from 9600 baud to 153,600 baud.
Smart card applications that support the 2-Wire protocol can also use CryptoMemory in the synchronous mode.
