Bus collision occurs during a STOP condition if:
a)
b)
The STOP condition begins with SDA asserted low. When SDA is sampled low, the SCL pin is
allow to float. When the pin is sampled high (clock arbitration), the baud rate generator is loaded
with SSPADD<6:0> and counts down to 0. After the BRG times out SDA is sampled. If SDA is
sampled low, a bus collision has occurred. This is due to another master attempting to drive a
data '0'
collision occurs. This is another case of another master attempting to drive a data '0'
(Figure
Figure 17-40: Bus Collision During a STOP Condition (Case 1)
Figure 17-41: Bus Collision During a STOP Condition (Case 2)
After the SDA pin has been de-asserted and allowed to float high, SDA is sampled low
after the BRG has timed out.
After the SCL pin is de-asserted, SCL is sampled low before SDA goes high.
