Block to read the 32-bit key that was received from the UDS tester.
Description
During a UDS seed/key sequence, a UDS tester first requests a seed from the ECU. Based on this seed, the UDS tester calculates the 32-bit key needed to unlock the resource, such as memory access. Once ready, the key is sent back to the ECU for verification. This 'UDS Get Key' block reads the value of the key that was received from the UDS tester.
This block is typically used in the function-call subsystem connected to the output of the 'UDS Verify Key Event' block.
