13.4.3
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 Master mode, the SCL and SDA lines are manipu-
lated by the MSSP hardware.
The following events will cause SSP Interrupt Flag bit,
SSPIF, to be set (SSP Interrupt if enabled):
• Start condition
• Stop condition
• Data transfer byte transmitted/received
• Acknowledge transmit
• Repeated Start condition

Master mode is enabled by setting and clearing the
appropriate SSPM bits in SSPCON and by setting the
SSPEN bit. Once Master mode is enabled, the user

The MSSP module, when configured in I
Master mode, does not allow queueing of
events. For instance, the user is not
allowed to initiate a Start condition and
immediately write the SSPBUF register to
imitate transmission, before the Start
condition is complete. In this case, the
SSPBUF will not be written to and the
WCOL bit will be set, indicating that a write
to the SSPBUF did not occur.
