PIC18F66K80 FAMILY

Master mode is enabled by setting and clearing the
appropriate SSPM bits in SSPCON1 and by setting the
SSPEN bit. In Master mode, the SCL and SDA 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
conditions. The Stop (P) and Start (S) bits are cleared
from a Reset or when the MSSP module is disabled.
Control of the I
set, or the 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 SSPBUF register to
initiate transmission before the Start

SSPBUF will not be written to and the
WCOL bit will be set, indicating that a write
