If TEN = 0, the temperature conversions update and the
resistors can be controlled manually. The user sets the
resistor in manual mode by writing to addresses 82h and
83h in Table 01 to control resistors 0 and 1, respectively.
AEN = 0 provides manual control of the temperature
index.
This byte is the temperature-calculated index used to
select the address of resistor settings in the look-up
tables.
Resistor 0 position values from 00h to FFh.
Resistor 1 position values from 00h to FFh.
This byte configures a maskable interrupt, determining
which event asserts a buffer 1 output (MINT set to 1, see
register 89h in Table 01). If any combination of
temperature, V
generate an interrupt, the corresponding bits are set to 1.
If interrupt generation is not desired, set all bits to 0.
CC
