35 "echo 0 > sda" you force SDA low and thus, data cannot be transmitted. The bus
39 succeed because SDA is still pinned low until you manually release it again
40 with "echo 1 > sda". A test with an automatic release can be done with the
46 The following fault injectors create situations where SDA will be held low by a
48 there are I2C client devices which detect a stuck SDA on their side and release
50 device deglitching and monitoring the I2C bus. It could also detect a stuck SDA
61 transmitted. Because the device will ACK its presence, this results in SDA
62 being pulled low by the device while SCL is high. So, similar to the "sda" file
