The CRC checksum includes the status nibble and the data nibbles and can be used to
check the validity of the decoded data. The sensor is available for the next sample 90µs
after the falling edge of the end pulse. The sampling time (when values are taken for
temperature compensation) is always defined as the beginning of the synchronization
period. During this period, the resulting data is always calculated from scratch.
The number of transmitted SPC nibbles is programmable to customize the amount of
information sent by the sensor. The frame contains a 16bit Hall value and an 8bit
temperature value in the full configuration.

The temperature is coded as an 8bit value. The value is transferred in unsigned integer
format and corresponds to the range between -55°C and +200°C, so a transferred value
of 55 corresponds to 0°C. The temperature is additional information and although it is not
