Notes For Table 11
1. Not all the temperature and pressure coefficients
must be used. When a coefficient is unused, the eight
LSB’s and the four MSB’s are replaced by 0.
2. The level steering and the alarm mode cannot be
active simultaneously because the levels bytes are
shared with the two modes.
3. If the alarm mode and the level steering are both
active, the level steering mode is dominant. The
firmware will run with the level steering mode, by
default.
4. If the DIGMO mode (VMO and CMO both active) is
active, the alarm will be automatically disabled by the
firmware.
5. At PNB_TNB address, the four MSB's correspond
to the address of the last pressure point and the four
LSB’s to the address of the last temperature point.
6. In the alarm_control variable, the selected
input is stored on the three MSB’s.
7. Pi and OFi are 10 bit values, right justified in 12
bits fields.
