If a Start, Restart, Stop or Acknowledge condition was
in progress when the bus collision occurred, the
condition is aborted, the SDA and SCL lines are
de-asserted, and the respective control bits in the
I2CCON register are cleared to ‘0’. When the user
services the bus collision Interrupt Service Routine,
and if the I
communication by asserting a Start condition.
The Master will continue to monitor the SDA and SCL
pins, and if a Stop condition occurs, the MI2CIF bit will
be set.
A write to the I2CTRN will start the transmission of data
at the first data bit, regardless of where the transmitter
left off when bus collision occurred.
In a Multi-Master environment, 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 I2CSTAT
register, or the bus is Idle and the S and P bits are
cleared.

16.13.1
When the device enters Sleep mode, all clock sources
to the module are shutdown and stay at logic ‘0’. If
Sleep occurs in the middle of a transmission, and the
state machine is partially into a transmission as the
clocks stop, then the transmission is aborted. Similarly,
if Sleep occurs in the middle of a reception, then the
reception is aborted.

For the I
stop on Idle or continue on Idle. If I2CSIDL = 0, the
module will continue operation on assertion of the Idle
mode. If I2CSIDL = 1, the module will stop on Idle.
