----------------------
+Introduction to incomplete transfers
+------------------------------------
+
+The following fault injectors create situations where SDA will be held low by a
+device. Bus recovery should be able to fix these situations. But please note:
+there are I2C client devices which detect a stuck SDA on their side and release
+it on their own after a few milliseconds. Also, there are external devices
+deglitching and monitoring the I2C bus. They can also detect a stuck SDA and
+will init a bus recovery on their own. If you want to implement bus recovery in
+a bus master driver, make sure you checked your hardware setup for such devices
+before.
+
+"incomplete_address_phase"
+--------------------------
 
 This file is write only and you need to write the address of an existing I2C
-client device to it. Then, a transfer to this device will be started, but it
-will stop at the ACK phase after the address of the client has been
+client device to it. Then, a read transfer to this device will be started, but
+it will stop at the ACK phase after the address of the client has been
 transmitted. Because the device will ACK its presence, this results in SDA
 being pulled low by the device while SCL is high. So, similar to the "sda" file
 above, the bus master under test should detect this condition and try a bus
 recovery. This time, however, it should succeed and the device should release
-SDA after toggling SCL. Please note: there are I2C client devices which detect
-a stuck SDA on their side and release it on their own after a few milliseconds.
-Also, there are external devices deglitching and monitoring the I2C bus. They
