Byte
Designation
Note
24
PNB_TNB
Number of temperature and pressure gaps. See Tables 4, 5,
and 6, and Figures 3 and 4.
25
n_factor
Temperature filter coefficient, four LSB's. Four MSB's must
all be zero.
26
Not used
This byte is not used.
27
ALARM low trigger
Level1 IO2/IO1
Value below which ALARM will go on.
Value of first level ([IO2, IO1]= 00-01). See Figures 5 & 7.
28
ALARM low output
Level2 IO2/IO1
Value of DIGMO during “ALARM low” condition.
Value of second level ([IO2,IO1] = 01-10). See Figures 5 and
7
29
ALARM high trigger
Level3 IO2/IO1
Value above which ALARM will go on.
Value of third level ([IO2,IO1]=10-11). See Figures 5 and 7.
30
ALARM high out level
Value of DIGMO during “ALARM high” condition. See
Figures 5 and 7.
31
ALARM control byte
IO1/IO2 control byte
Four LSB's are unused
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.
32
ClkTC1
Value of Cadj at low temperature (Don’t change; factory set).
33
ClkTC2
Value of Cadj at mid temperature (Don’t change; factory set).
34
ClkTC3
Value of Cadj at high temperature Don’t change; factory set).
35
Ctemp1
First Cadj temperature point, eight MSB’s of the 10 bit
internal temperature value (set at factory; do not change).
36
Ctemp2
Second Cadj temperature point, eight MSB’s of the 10 bit
internal temperature value (set at factory; do not change).
37-38
Not used
These bytes are not used by the firmware and are available
to the user.
39
CLKgntp
Setting for temperature amplifier for clock temperature
adjustment temperature reading (set at factory; do not
change).
40-41
Faultval
Value sent to output if checksum test fails is a 10 bit value.
42-46
Not Used
These bytes are not used by the firmware and are available
to the user.
47
Checksum
EEPROM checksum; value needed to make all bytes add to
0FFh. Must be set by user if checksum test is active.
