Data Transmit Format 1
Data Transmit Format 2
Data Receive Format
To receive data, the master transmitter changes to a receiver immediately after the first
acknowledgement. The slave receiver changes to a transmitter.
The end condition is always created by the master.
Optional Data Transmit Format (Automatic Increment Mode)
In this way, sub-addresses are automatically incremented from the specified sub-address and data are
set.
