PPS Support
All Atmel
Selection (PPS) protocol, Section 7 of ISO 7816-3. This section only applies to these larger devices; CryptoMemory
devices with memory sizes 16-Kbit or smaller do not support PPS.
At the end of an ATR sequence, subsequent to either a cold or a warm reset initiated by the reader, the device will be
expecting either a ‘Class’ byte as part of a command header, or the initial character, PPSS, of a PPS request. If the
device receives a byte = $FF, it will process subsequent incoming bytes as a PPS request. In all other cases, it will
proceed with command processing. There are 4 bytes that comprise a PPS request or response;
• Initial Character PPSS. Always equal to $FF
• Format Character PPS0. CryptoMemory supports two response values for PPS0, $00 and $01. See ISO 7816 for
• Parameter Character PPS1. Encodes Fn and Dn in the same manner as TA(1) in the ATR
• Checksum PCK
The following table shows the PPS1 values supported by CryptoMemory devices with memory sizes 32-Kbits and
above.
Table 33. PPS1 Values Atmel CryptoMemory Supports
After the ATR, the reader will have the choice of proceeding with commands using default values of F=372 and D=1
(9600-baud at 3.5712MHz), or negotiating values Fn and Dn through a PPS exchange. Following, are four examples of
PPS requests and responses:
