Table 02h, Register 81h: Tindex
POWER-ON VALUE
READ ACCESS
WRITE ACCESS
MEMORY TYPE
Holds the calculated index based on the Temperature Measurement. This index is used for the address during lookup of tables 04h
and 05h. Temperature measurements below -40°C or above 102°C are clamped to 00h and C7h, respectively. The calculation of
Tindex is as follows:
For the two temperature-indexed LUTs, the index used during the lookup function for each table is as follows:
Tab l e 04h M OD
Tab l e 05h AP C
Table 02h, Register 82h: MOD DAC
POWER-ON VALUE
READ ACCESS
WRITE ACCESS
MEMORY TYPE
The digital value used for MOD and recalled from Table 04h at the adjusted memory address is found in Tindex. (R.O.)
This register is updated at the end of every temperature conversion.
Table 02h, Register 83h: APC DAC
POWER-ON VALUE
READ ACCESS
WRITE ACCESS
MEMORY TYPE
The digital value used for APC reference and recalled from Table 05h at the adjusted memory address found in Tindex. (R.O.)
This register is updated at the end of the temperature conversion.
