TEN
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.

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