Bit 3 - 2 - STBY_SAMP_TIME[1:0] - Determines the time to take a single sample for sensor inputs enabled in Standby

as shown in Table 5-41.

Bits 1 - 0 - STBY_CY_TIME[2:0] - Determines the desired sensing cycle time for sensor inputs enabled during Standby,

as shown in Table 5-42. This control is also used to determine programmed cycle time in the Combo state (see Section

4.3.1.3, "Combo State Sensing Settings"). All enabled channels are sampled at the beginning of the sensing cycle. If

additional time is remaining, the device is placed into a lower power state for the remainder of the sensing cycle.

APPLICATION NOTE: The programmed sensing cycle time (STDBY_CY_TIME[1:0] is only maintained if the actual

time to take the samples is less than the programmed cycle time. The STBY_AVG[2:0] bits
