Two bytes are sent to the slave but are not
processed by the slave
1) Available in TTR compatibility mode only.
2) Bit 7: 0 = no error / 1 = error
Bit 6: 0 = Trip Point 1 not activated / 1 = Trip Point 1 activated
Bit 5: 0
Bit 4: 0
The measurement value is given as a 12-bit value. Byte 1 / Bit 3 represents the MSB,
Byte 2 / Bit 0 the LSB
p [mbar] = 10
Measurement_Value / 482 - 4.778
p [Torr] = 10 Measurement_Value / 482 - 4.9029
p [Pa] = 10 Measurement_Value / 482 - 2.778
