This section describes a standard sequence of events
for the MSSPx module configured as an I
10-bit Addressing mode.

Preliminary
24.5.5
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 SCLx line is held low are the
same. Figure 24-20 can be used as a reference of a
slave in 10-bit addressing with AHEN set.
Figure 24-21 shows a standard waveform for a slave
transmitter in 10-bit Addressing mode.
