Clock Arbitration
Sleep Operation
Effect of a Reset
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 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
