9.2.5
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
P bit is 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.
FIGURE 9-9:
9.2.6
In Multi-Master mode, the interrupt generation on the
detection of the START and STOP conditions allows
the determination of when the bus is free. The STOP
(P) and START (S) bits are cleared from a RESET or
when the MSSP module is disabled. Control of the I
bus may be taken when bit P (SSPSTAT<4>) is set, or
the bus is idle with both the S and P bits clear. When
the bus is busy, enabling the SSP Interrupt will gener-
ate the interrupt when the STOP condition occurs.

The following events will cause the SSP Interrupt Flag
bit, SSPIF, to be set (an SSP interrupt will occur if
enabled):
• START condition
• STOP condition
• Data transfer byte transmitted/received
• Acknowledge transmit
• Repeated START
In Multi-Master operation, the SDA line must be moni-
tored for arbitration to see if the signal level is the
expected output level. This check is performed in hard-
ware, with the result placed in the BCLIF bit.
The states where arbitration can be lost are:
• Address Transfer
• Data Transfer
• A START Condition
• A Repeated START Condition
• An Acknowledge Condition
