8.2.15
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 gen-
erator (BRG) is suspended from counting until the SCL
pin is actually sampled high. When the SCL pin is sam-
pled 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
