8.2 Read transfer
Figure 13. I2C read transfer
Eight bytes can be read at a time (please refer to the to the pages ??? to ??? for the meaning of each bit).
The master has always the possibility to read less than eight registers by not sending the acknowledge bit
and then generating a stop condition after having read the needed amount of registers.
There are two typical read access :
– read only the first register rds_int to check the interrupt bit.
– read the first five registers rds_int, rds_qu, rds_corrp, rds_bd_h, rds_bd_l to get the RDS data
The registers are read in the following order : rds_int, rds_qu, rds_corrp, rds_bd_h,rds_bd_l, rds_bd_ctrl,
sinc4reg, testreg.
Figure 14. I2C read access example 1: read of 5 bytes
