INTR
When INTR = 11, the interrupt is generated immediately following the SMBus write operation. Operation then
behaves in an SMB-Alert mode, and the software set interrupt may be cleared by an SMB-Alert cycle.
Note:

Interrupts are based on the value of Channel 0 only.

INTR_STOP
Reserved. Write as 0.
Stop ADC integration on interrupt. When high, ADC integration will stop once an interrupt is asserted. To
resume operation (1) de-assert ADC_EN using CONTROL register, (2) clear interrupt using COMMAND
register, and (3) re-assert ADC_EN using CONTROL register. Note: Use this bit to isolate a particular
condition when the sensor is continuously integrating.
INTR Control Select. This field determines mode of interrupt logic according to Table 7, below.
Interrupt persistence. Controls rate of interrupts to the host processor as shown in Table 8, below.
