Abstract
A procedure is provided for identifying an operating mode of a device, such as an EEPROM memory that communicates according to a communication protocol, such as 'IC' (Inter Integrated Circuit). The signal is an 'ACK' or “ACKNOWLEDGE” signal. At least one operating mode of a device is identified by a time lag from the time the signal (ACK) is transmitted relative to the time foreseen by the protocol for the signal. This approach can be used to verify that the test mode commands (read or write) have been taken into account correctly.
