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).

Note:
Falling edge of ninth clock

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