Note
Number of temperature and pressure gaps. See Tables 4, 5,
and 6, and Figures 3 and 4.
Temperature filter coefficient, four LSB's. Four MSB's must
all be zero.
This byte is not used.
Value below which ALARM will go on.
Value of first level ([IO2, IO1]= 00-01). See Figures 5 & 7.
Value of DIGMO during “ALARM low” condition.
Value of second level ([IO2,IO1] = 01-10). See Figures 5 and
7
Value above which ALARM will go on.
Value of third level ([IO2,IO1]=10-11). See Figures 5 and 7.
Value of DIGMO during “ALARM high” condition. See
Figures 5 and 7.
Three bits needed for choice of input for ALARM detection
(TPO, IAO, GNO, VMO, IO1 or IO2).
Two bits needed for choice of input for LEVEL-steering
(TPO, IAO, GNO or VMO).
The above bits are multiplexed according to the mode. If both
CMO and VMO are active, then alarm is not active.
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 by the firmware and are available
to the user.
Setting for temperature amplifier for clock temperature
adjustment temperature reading (set at factory; do not
change).
Value sent to output if checksum test fails is a 10 bit value.
These bytes are not used by the firmware 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.
