13.4.15
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
be taken when the P bit (SSPSTAT register) 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.
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.
Arbitration can be lost in the following states:
• Address transfer
• Data transfer
• A Start condition
• A Repeated Start condition
• An Acknowledge condition
13.4.16
Multi-Master mode support is achieved by bus arbitra-
tion. When the master outputs address/data bits onto
the SDA pin, arbitration takes place when the master
outputs a ‘1’ on SDA, by letting SDA float high and
another master asserts a ‘0’. When the SCL pin floats
high, data should be stable. If the expected data on

If a transmit was in progress when the bus collision
occurred, the transmission is halted, the BF bit is
cleared, the SDA and SCL lines are de-asserted, and
the SSPBUF can be written to. When the user services
the bus collision interrupt service routine, and if the I
bus is free, the user can resume communication by
asserting a Start condition.
If a Start, Repeated Start, Stop, or Acknowledge
condition was in progress when the bus collision

The master will continue to monitor the SDA and SCL
pins. If a Stop condition occurs, the SSPIF bit will be
set.
A write to the SSPBUF will start the transmission of
data at the first data bit, regardless of where the trans-
mitter left off when the bus collision occurred.
In Multi-Master mode, the interrupt generation on the
detection of Start and Stop conditions allows the
determination of when the bus is free. Control of the I
bus can be taken when the P bit is set in the SSPSTAT
register, or the bus is idle and the S and P bits are
cleared.
