H.2.
Table H-33. Definition of the CountValue field in the response to the counter command
The equivalent decimal value of the counter can be determined using the counter calculator in the Atmel Crypto Evaluation
Studio, (ACES) configuration environment. Sample code is also available for decoding the counter value. Both are available
as free downloads at www.atmel.com.
Personalizing the Monontonic Counters
The counter registers are personalized with initial values prior to locking the configuration memory. The standard Serial
EEPROM write commands are used to write the configuration memory (see Section 5.3.3). The lock command is used to lock
the configuration memory (see Section 7.19).
The initial values can be determined using the counter calculator in the ACES configuration environment. ACES is available
for free download at www.atmel.com.
