1.5.2 Data Structures

Table 1-5. Group Configuration
Parameter	Size	Range/Options	Usage
num_key_sensors	2 bytes	1-to-65535	The number of sensor keys in the group
sensor_touch_di	1 byte	0-to-255	The number of repeat measurements to confirm touch detection and out-of-touch detection
sensor_max_on_time	1 byte	0 (Disabled), 1-to-255	The number of timer periods with sensor In Detect before automatic ‘recal’
sensor_anti_touch_di	1 byte	0 (Disabled), 1-to-255	The number of repeat measurements to confirm anti-touch recalibration required
sensor_anti_touch_recal_thr	1 byte	0-to-5	Scale-down of touch threshold to set anti-touch threshold. 0 = 100% Touch Threshold 1 = 50% 2 = 25% 3 = 12.5% 4 = 6.25% 5 = Maximum Recalibration
sensor_touch_drift_rate	1 byte	0 (Disabled), 1-to-255	The number of timer periods to countdown between towards touch drifts
sensor_anti_touch_drift_rate	1 byte	0 (Disabled), 1-to-255	The number of timer periods to countdown between away from touch drifts
sensor_drift_hold_time	1 byte	0 (Disabled), 1-to-255	The number of timer periods to stop drifting after touch event
sensor_reburst_mode	1 byte	0 = None 1 = Unresolved (Quick reburst) 2 = All	None – Reburst is never set, measurements according to application schedule. Unresolved – Reburst is set, all sensors suspended except those in same AKS as the target sensor. All – Reburst is set, no sensors are suspended.

Table 1-6. Individual Sensor Configuration
Parameter	Size	Range/Options	Usage
channel_threshold	1 byte	0-to-255	Minimum signal delta indicating touch contact
channel_hysteresis	1 byte	0 (50%)-to-4 (3.125%)	Reduction of touch threshold to de-bounce when filtering out removed touch contact
channel_aks_group	1 byte	0-to-255	Grouping of key sensors controlling simultaneous touch detect
