Standby Configuration Register

The Standby Configuration register controls averaging and sensing cycle time for sensor inputs enabled in Standby. This

maintain normal functionality in the Active state.

Bit 7 - AVG_SUM - Determines whether the sensor inputs enabled in Standby will average the programmed number of

samples or whether they will accumulate for the programmed number of samples.

• ‘0’ - (default) - The Standby enabled sensor input delta count values will be based on the average of the pro-

grammed number of samples when compared against the threshold.

• ‘1’ - The Standby enabled sensor input delta count values will be based on the summation of the programmed

number of samples when compared against the threshold. Caution should be used with this setting as a touch

may overflow the delta count registers and may result in false readings.

Bits 6 - 4 - STBY_AVG[2:0] - Determines the number of samples that are taken for all Standby enabled channels during

the sensing cycle as shown in Table 5-37. All samples are taken consecutively on the same channel before the next

channel is sampled and the result is averaged over the number of samples measured before updating the measured

results.

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 5-38.
