All rights reserved. Product data sheet Rev. 3.3 — 5 April 2019 COMPANY PUBLIC 430733 90 / 132 11.8.3 GetValue The GetValue command allows reading the currently stored value from the Value file. The value is always represented LSB first. The GetValue command requires a preceding authentication with the key specified for Read, Write or ReadWrite access. Secure messaging applies to the command according to the file communication mode setting. If free GetValue is configured for the Value file, the GetValue command does not need any prior authentication and CommMode.Plain is applied. After updating a value file value but before issuing the CommitTransaction command, the GetValue command will always retrieve the old, unchanged value which is still the valid one. aaa-032213 PICC to PCD PCD to PICC CLA 90 CMD 6C P1 00 P2 00 Lc XX 1 1 1 1 1 1 Le 00 1 FileNr Response data Value 4 SW1 status 1 SW2 1 Figure 30.
