In I
reload value is placed in the lower 7 bits of the
SSPADD register (Figure 15-17). When a write occurs
to SSPBUF, the baud rate generator will automatically
begin counting. The BRG counts down to 0 and stops
until another reload has taken place. The BRG count is
decremented twice per instruction cycle (T

Once the given operation is complete (i.e., transmis-

clock will automatically stop counting and the SCL pin
will remain in its last state.
