TEN
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
AEN = 0 is a test mode setting and provides manual
control of the temperature index (Table 01, address 81h).

Interrupt enable
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, VCC, MON1, MON2, or MON3 is desired to
generate an interrupt, the corresponding bits are set to 1.
If interrupt generation is not desired, set all bits to 0.
