17.4.10.1 WCOL Status Flag
1997 Microchip Technology Inc.
If the user writes the SSPBUF when a Repeated Start sequence is in progress, then WCOL is
set and the contents of the buffer are unchanged (the write doesn’t occur).

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