8.4.2.2 Transparent Hysteresis-Style Comparison Mode

The transparent hysteresis-style comparison mode is typically used when a single digital signal is desired that indicates whether the input light is higher than or lower than a light level of interest. If the result register is higher than the high-limit register for a consecutive number of events set by the fault count field, the INT line is set to active, the flag high field is set to 1, and the flag low field is set to 0. If the result register is lower than the low-limit register for a consecutive number of events set by the fault count field, the INT line is set to inactive, the flag low field is set to 1, and the flag high field is set to 0. The INT pin and flag high and flag low fields do not change state with configuration reads and writes. The INT pin and flag fields continually report the appropriate comparison of the light to the low-limit and high-limit registers. The device does not respond to the SMBus alert response protocol while in either of the two transparent comparison modes (configuration register, latch field = 0). The behavior of this mode, along with the conversion ready is summarized in Table 8-3. Note that Table 8-3 does not apply when the two threshold low register MSBs (LE[3:2] from Table 8-11) are set to 11.
