PRODUCTION DATA.
After power-up, the internal registers must be initialized to their default values through a hardware reset by applying a high pulse on the RESET pin (of durations greater than 10 ns), as shown in Figure 47. Notice that when hardware reset is applied for "first time after powering up the device", the SEN pin must be in low logic state. However, this requirement is applicable only for first hardware reset after power-up. Any subsequent hardware reset does not require SEN to be in low logic state and works independent to it. If required, the serial interface registers can be cleared during operation either:
