2011 Microchip Technology Inc.
After the SDAx pin has been deasserted and
allowed to float high, SDAx is sampled low after
the BRG has timed out.
After the SCLx pin is deasserted, SCLx is
sampled low before SDAx goes high.

The Stop condition begins with SDAx asserted low.
When SDAx is sampled low, the SCLx pin is allowed to
float. When the pin is sampled high (clock arbitration),
the BRG is loaded with SSPxADD<6:0> and counts
down to 0. After the BRG times out, SDAx is sampled. If
SDAx is sampled low, a bus collision has occurred. This
is due to another master attempting to drive a data ‘0’
(Figure
SDAx is allowed to float high, a bus collision occurs. This
is another case of another master attempting to drive a
data ‘0’
19-33). If the SCLx pin is sampled low before
(Figure
SCLx goes low before SDAx goes high,
