14.3.7
In I
reload value is placed in the SSPADD register
(Figure 14-17). When a write occurs to SSPBUF, the
Baud Rate Generator will automatically begin counting.
Once
transmission of the last data bit is followed by ACK), the
internal clock will automatically stop counting and the
SCL pin will remain in its last state.
