value if operating in asynchronous mode. The CyrptoMemory device will always output all 8
bytes in response to the asynchronous ATR command regardless of the contents of the register.
Once the asynchronous mode has been selected, it is not possible to switch to the synchronous
mode without powering off the device.
Figure 6-2.
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 CryptoMemory devices 32-
Kbits and larger in user memory. 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 selec-
tion 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 syn-
chronous mode.
