Master mode is enabled by setting and clearing the
appropriate SSPM bits in SSPxCON1 and by setting
the SSPEN bit. In Master mode, the SCLx and SDAx
lines are manipulated by the MSSP hardware if the
TRIS bits are set.
Master mode of operation is supported by interrupt
generation on the detection of the Start and Stop con-
ditions. The Stop (P) and Start (S) bits are cleared from
a Reset or when the MSSP module is disabled. Control
of the I
bus is Idle, with both the S and P bits clear.
In Firmware Controlled Master mode, user code
conducts all I
Stop bit conditions.
Once Master mode is enabled, the user has six
options.

allowed to initiate a Start condition and
immediately write the SSPxBUF register to
initiate transmission before the Start condi-
tion is complete. In this case, the
SSPxBUF will not be written to and the
WCOL bit will be set, indicating that a write
to the SSPxBUF did not occur.
