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 1 can
be used as a reference of a client in 10-bit addressing with AHEN set.
Figure 2
shows a standard waveform for a client transmitter in 10-bit Addressing mode.
