Note
Number of temperature and pressure gaps.
Temperature filter coefficient, four LSB's. Four MSB's
must all be zero.
This byte is not used.
Value of Cadj at low temperature (Don’t change; factory
set).
Value of Cadj at mid temperature (Don’t change; factory
set).
Value of Cadj at high temperature Don’t change; factory
set).
First Cadj temperature point, eight MSB’s of the 10 bit
internal temperature value (set at factory; do not
change).
Second Cadj temperature point, eight MSB’s of the 10
bit internal temperature value (set at factory; do not
change).
These bytes are not used and are available to the user.
Setting for temperature amplifier for clock temperature
adjustment temperature reading (factory set, do not
change).
Value sent to output if checksum test fails is a 10 bit
value.
These bytes are not used and are available to the user.
EEPROM checksum; value needed to make all bytes
add to 0FFh. Must be set by user if checksum test is
active.
