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
Q2 and Q4 clocks. In I
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).
