25.2.3.6.4 10-Bit Addressing with Address or Data Hold
Reception using 10-bit addressing with AHEN
         or DHEN set is the same as with 7-bit modes. The only difference is the need to
         update the SSPxADD register using the UA
         bit. All functionality, specifically when the CKP
         bit is cleared and SCL line is held low, are the same. Figure 25-20 can
         be used as a reference of a client in 10-bit addressing with AHEN set.
      Figure 25-21 shows a standard waveform for a client transmitter in 10-bit Addressing mode.
