Freescale Interconnect Bus
16.5 Message validation
Technical Data
292
The communication between the MCU and the selected device is valid
when the MCU reads a pull data field having correct codes (excluding
the codes ‘111’ and ‘000’) followed by a square wave signal, having a
frequency of 20kHz, contained in the end-of-frame information.
An MI Bus error is detected when the pull field contains the code ‘111’
followed by the end-of-frame permanently tied to logical state ‘1’. This
means that the communication between the MCU and the selected
device was not accomplished.
