Figure 5. Digital Interface at Normal Operation Mode

7.5 Waveform – Digital Interface at Extended Mode

In the extended mode, the digital interface needs four clocks for one data bit due to the internal structure. During this time, the device is able to

handle internal signals for special access (e.g. the easy zap interface).
