Hello TI,
It seems that the I2C register map as described in the datasheet (SPRS680A–OCTOBER 2010–REVISED MARCH 2011) and also TRM do not match with the one defined in Spectrum digital I2C library for their EVM (evaluation board for davinci 816x).
Below is an extract from their evm816x.h include file, and it is completely different from the one as described in the documentation.
So we would like to know which is the good register map : the one in the documentation or in the example ?
Thanks by advance,
jar
