Concerto Documentation Question/Issue

I think I found an issue with the I2C documentation on the Technical Reference manual for the F28M35x

Using SPRUH22C, all of the figures from 24-7 to 24-12 write five bits to the I2CMCS (for example ---0-111 on Figure 24-7)  but according to the document only the least significant four bits do something (Table 24-5).

What say you?

    William,

    Looks like the documentation is in error. The fifth bit mentioned in the diagrams was meant to be the R/S field (bit 0) in the I2CMSA register. Unfortunately, the diagrams don't show the correct values for that bit either. The correct way to set the transmit/receive direction is to write to I2CMSA at the start of a transmit or receive sequence. You can find the correct bit values for the different conditions in Table 24-6.

    We will update the diagrams to show the correct I2CMSA/I2CMCS sequence.

    Thanks,
