Read transfer
Figure 18. I
Eight bytes can be read at a time (please refer to
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:
●
●
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.
