for the MSSP module configured as an I
10-bit Addressing mode.

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 SSPADD register
using the UA bit. All functionality, specifically when the
CKP bit is cleared and SCL line is held low are the
same. Figure 23-20 can be used as a reference of a
slave in 10-bit addressing with AHEN set.
Figure 23-21 shows a standard waveform for a slave
transmitter in 10-bit Addressing mode.
