The settings are the thresholds (from On to Off, and from Off to On), the gain and the mask function of the each switch operation (On / Off / Continuous touch). GAIN_SIN*[3:0] : Setting for the gain : This register is for setting the gain of AFE. The smaller the value of this register is, the higher the gain is. Adjustment range : 0x1 ≤ GAIN_SIN ≤ 0xF The sensor which setting value is 0 has no switch function. ON_TH_SIN*[7:0] : The threshold from Off to On : This register is the threshold from Off to On. This value is compared to the register SIN_DATA. If the value of this register is larger than SIN_DATA, the On operation is detected. OFF_TH_SIN*[7:0] : The threshold from On to Off : This register is the threshold from On to Off. This value is compared to the register SIN_DATA. If the value of this register is smaller than SIN_DATA, the Off operation is detected. Adjustment range : 0x00 < OFF_SIN* < ON_SIN* < 0xFF The sensor which setting value is out of this range is unusable for switch operation. MSK_ON_SIN*, MSK_OFF_SIN*, MSK_CONT_SIN* : Mask for the switch operation : This register is the mask function of the each switch operation (On / Off / Continuous touch). If the mask function is enabled, the register for detection of switch operation is disabled. 1 : Mask function is enable. 0 : Mask function is disable (default).

The monitor’s purpose is to prevent erroneous stop of detection of the AFE. If the state that the AFE scan is stopped in the case that the monitor function is enabled is detected, the AFE scan will be self-restarted. Monitor function is executed about 300 msec. 1 : Monitor function is enabled. 0 : Monitor function is disabled (default).
