Masks all ALERT interrupts when high.
Standby mode control bit. If high, the device immediately stops converting and
enters standby mode. If low, the device converts.
Masks remote DX4 interrupts when high.
Masks remote DX3 interrupts when high.
Masks remote DX2 interrupts when high.
Masks remote DX1 interrupts when high.
