If TEN = 0, 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 is a test mode setting and provides manual
control of the temperature index (Table 01, address 81h).
This byte is the temperature-calculated index used to
select the address of resistor settings in the look-up
tables (Tables 02 and 03, addresses 80h through C7h).
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
, MON1, MON2, or MON3 is desired to
