3.2. I
The control interface to the Si570 is an I
consists of a bidirectional serial data line (SDA) and a serial clock input (SCL). Both lines must be connected to the
positive supply via an external pullup. Fast mode operation is supported for transfer rates up to 400 kbps as
specified in the I
Figure 5 shows the command format for both read and write access. Data is always sent MSB. Data length is 1
byte. Read and write commands support 1 or more data bytes as illustrated. The master must send a Not
Acknowledge and a Stop after the last read data byte to terminate the read command. The timing specifications
