Control interface

125

The interface also supports auto-increment indexing. After the first data byte has been

transferred, the index is automatically incremented by 1. The master can therefore send

data bytes continuously to the slave until the slave fails to provide an acknowledge or the

master terminates the write communication with a stop condition. If the auto-increment

feature is used the master does not have to send address indexes to accompany the data

bytes.

Further details of the control interface protocol can be found in the MIPI Alliance Standard

for Camera Serial Interface 2 (CSI-2).
