Remark: Transfer of data can be stopped at any moment by a STOP condition. When this occurs, data present at the latest acknowledge phase is valid (output mode).
It is assumed that the command byte has previously been set to ‘00’ (read input port register).
This figure eliminates the command byte transfers and a restart between the initial slave address call and actual data transfer from P port (see
Figure
13).
