AUTO_SLEEP_SET
：
Auto SLEEP Mode Setting
As shown in Figure 33 below,
Figure 33: AUTO_SLEEP_SET option
IS31SE5117 integrates AUTO_SLEEP function and the entering time could be configured. System will enter into
SLEEP Mode when no action in touch key. It will be waked up by any key action. In some applications that require
low power consumption, it can be set to SLEEP mode automatically.
KEY0~KEY10 is enabled to exit SLEEP Mode (Click SLEEP button in Figure 17 to enter into SLEEP Mode in GUI
interface). Enable the corresponding key and system will be waked up as key value arrives the wake up threshold
(WAKE_THRESHOLD)
WAKE_THRESHOLD_SET is used to set the key threshold for waking up from SLEEP Mode. Input data in box
and press Enter or Tab key, or move the cursor to another location will set up the threshold.

CALIB_SET
：
Calibration Setting
As shown in Figure 34 below,
Figure 34: CALIB_SET option
CALIB_SAMPLE_CNT sets times for auto-calibrate cycle. The influence of parasitic capacitance shift on touch
key will be reduced by calibrating.
When the variety of continuous sampling is negative and over the negative threshold (NEG_DELTA_TH), the
corresponding key will be forced calibrating.
NEG_DELTA_TH is used to set negative threshold.
N_CAL_NEG_TH is the negative threshold for forced calibration.
