24.6.2
Clock arbitration occurs when the master, during any
receive, transmit or Repeated Start/Stop condition,
releases 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<7:0> 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 24-25:
24.6.3
If the user writes the SSPBUF when a Start, Restart,
Stop, Receive or Transmit sequence is in progress, the
WCOL is set and the contents of the buffer are
unchanged (the write does not occur). Any time the
WCOL bit is set it indicates that an action on SSPBUF
was attempted while the module was not Idle.

WCOL STATUS FLAG
Because queueing of events is not
allowed, writing to the lower 5 bits of
SSPCON2 is disabled until the Start
condition is complete.
