Das Szenario
I2C reads are visually clearer as timing diagrams than as prose. The repeated start and ACK/NACK phases are where firmware and hardware teams most often talk past each other.
WaveDrom-compatible timing diagram for an I2C register read with address, repeated start, data bytes, ACK, and NACK phases.
