6.3
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.
6.3.1
There are three different MI BUS error types which are detected by the selected slave device and
are not mutually exclusive. The MCU cannot determine which error occurred.
6.3.2
There is a fourth error that can be detected by the MCU. This error causes the noise flag (NF) to
be asserted in the S2SR1 register during the push field sequence.

MI BUS serial system monitors the bus via on-chip hardware at the RXD pin
at the same time as sending data. A bit error is detected at that bit time when
the value monitored is different from the bit value sent.
