Clock arbitration occurs when the master, during any
receive, transmit or repeated START/STOP condition,
de-asserts the SCL pin (SCL allowed to float high).
When the SCL pin is allowed to float high, the baud rate
generator (BRG) is suspended from counting until the

Advance Information

Hold off BRG until SCL is sampled high.
SCL pin is actually sampled high. When the SCL pin is
sampled high, the baud rate generator is reloaded with
the contents of SSPADD<6:0> and begins counting.
This ensures that the SCL high time will always be at
least one BRG rollover count in the event that the clock
is held low by an external device (Figure 9-22).
