Appendix N. Atmel ATAES132 Command Response Time
The typical and maximum time required for the ATAES132 to process an extended command is shown in Table N-1. The
response time is the time from sending the last bit of the last byte of the command block to the command memory buffer until
the STATUS register (or I
required for an error free command to be processed on a typical device at room temperature. The "Maximum" response time is
the worst case time for the command to be processed over the specified temperature range. (With or without an error
condition, whichever results in the worst response time)
