While in Sleep mode, the I
addresses or data and when an address match or
complete byte transfer occurs, wake the processor
from Sleep (if the MSSPx interrupt is enabled).
15.6.11
A Reset disables the MSSPx module and terminates
the current transfer.

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
MSSPx module is disabled. Control of the I
be taken when the P bit of the SSPxSTAT register is
set, or the bus is Idle, with both the S and P bits clear.
When the bus is busy, enabling the SSPx interrupt will
generate the interrupt when the Stop condition occurs.
In multi-master operation, the SDAx line must be
monitored for arbitration to see if the signal level is the
expected output level. This check is performed by
hardware with the result placed in the BCLxIF bit.
The states where arbitration can be lost are:
• Address Transfer
• Data Transfer
• A Start Condition
• A Repeated Start Condition
• An Acknowledge Condition
