In I
located in the lower 7 bits of the SSPADD register
(Figure 13-11). When the BRG is loaded with this
value, the BRG counts down to 0 and stops until
another reload has taken place. The BRG count is
decremented twice per instruction cycle (T

reloaded automatically. If clock arbitration is taking
place, for instance, the BRG will be reloaded when the
SCL pin is sampled high (Figure 13-12).
