14.2.2.2. Diagnostic Reporting, Channel 1
The diagnostic can be reported through the 12 bit payload of channel 1, and not only through the status
bit Status[0].
The EEPROM parameters SERIALERROR controls the diagnostic reporting through channel 1 as follow:
If SERIALERROR =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 SERIALERROR >0, the channel1 payload contains the value Channel1 = (4088 + SERIALERROR])
14.2.2.3. 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.
14.2.2.4. Diagnostic Debouncing
The Diagnostic Reporting is Debounced. The debouncing paramater are user-programmable, by steps of
approximately 6 ms.
14.2.3. Pause pulse
A pause pulse, as defined by the standard, is present at the end of every frame.
The pause pulse mode can 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.
14.2.4. Fast Channel CRC
The 90367 features the new recommended implementation and optional the legacy implementation
14.3. Slow Channel
14.3.1. 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.
