8I2C Transfer Mode
This interface consists of three lines: a serial data line (SDA), a bit clock (SCL), and a slave address select (SA).
The interface is capable of operating in fast mode (up to 400kbits/s) but also at lower rates (<100kbits/s).
Data transfers follow the format shown in Fig.8 . After the START condition (S), a slave address is sent. The
address is 7 bits long followed by an eighth bit which is a data direction bit (R/_W).
A ’zero’ indicates a transmission (WRITE), a ’one’ indicates a request for data (READ).
The slave address of the chip is set to 001000S, where S is the least significant bit of the slave address set
externally via the pin SA_DATAOUT. This allows to choose between two addresses in case of conflict with an-
other device of the radio set.
Each byte has to be followed by an acknowledge bit (SDA low).
Data is transfered with the most significant (MSB) bit first.
A data transfer is always terminated by a stop condition (P) generated by the master.
