H A Dgpio-fault-injection.rst33 By reading this file, you get the current state of SDA. By writing, you can
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
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
65 SDA after toggling SCL.
73 The injector will again stop at one ACK phase, so the device will keep SDA low
82 This is why bus recovery (up to 9 clock pulses) must either check SDA or send
