If EE_REPORT[2:0]=0, the channel 1 reports the angle, and not the diagnostic, as if no diagnostic.

The error is reported only thanks to the Status bits.

If EE_REPORT[2:0]>0, the channel1 payload contains the value Channel1 = (4088 + EE_REPORT[2:0])

13.2.2.3. Diagnostic Reporting Time

The Diagnostic Reporting Time is programmable (defined as multiple of a macro-cycle unit time).

A macro-cycle is a sequence of 20 angle acquisitions, and has a duration of approximately 6 ms.

13.2.2.4. Diagnostic Debouncing

The Diagnostic Reporting is Debounced. The debouncing paramater is user-programmable, by steps of

approximately 6 ms.

13.2.3. Pause pulse

A pause pulse, as defined by the standard, is present at the end of every frame.

The pause pulse mode cannot be disabled.

The pause pulse lenght is adjusted by the circuit so that the frame period is constant.

The field sensing and the frame synchro pulse are in sync.

13.2.4. Fast Channel CRC

The MLX90366 features the new recommended implementation.

13.3. Slow Channel

13.3.1. Enhanced Serial Message

The circuit encodes the slow messages according the Enhanced Serial Message Format as specified at

Chapter 5.2.4.3 of the SENT norm, except for the following restriction:

The configuration bit is always 0, meaning that the payload consists in 12-bit data and 8-bit message ID.
