Thanks for dropping by, well, reading is not enough, I'm trying to achieve something on my own, you mean having fully understood or been able to decipher some acronyms, figures, equations etc.? unfortunately, no. I haven't found application notes to the IC itself only general to I2C bus, and was about to write to TI but not expecting luck, gave it up!
Anyway, some hours ago, I found a much better source and since you're kindly volunteering here, lots of thanks again, You can perhaps help me in a certain part.
The guy did a great job availing 3 examples one is programming the SN761662, similar to mine. I tried to compare things, I don't understand the setting (calculation) of divider bits DB1 DB2.
I also think the guy swapped DB1 and DB2 bytes as he says: "The third byte(DB2) is the programmable divider, in this byte the first bit is not used 0"
But in the datasheets DB1 starts with 0, whereas DB2 starts with N7.
Trying to understand his procedure of writing the binary equivalent byte for the bits in the (SN761662, pp11, table 1) (don't guess I'm a math dummy!), he says "the second bit is divided by the power of 2^1, the third bit is divided by the power of 2^2 the fourth.. etc."
I am stuck here! I don't know where the bit N14, N13, N12 number that is divided by 2^2, ...etc!
In the datasheet table 2 description: N=N14x2^14. Let's calculate: 14*(2^14)=229376! That wouldn't lead to an 8 bit zeros and ones.
