33 / 50 page  33 AT42QT1111-MU / AT42QT1111-AU [DATASHEET] 9571C–AT42–05/2013 The values for the “IN_DETECTn” and “OUT_DETECTn” nibbles are listed in Table 7-11. Default IN_DETECTn value: 8 (100% PWM – on) Default OUT_DETECTn value: 0 (0% PWM – off) 7.13 Address 16: LED Detect Hold Time When a key is touched, if the “Detect” outputs and “Key to LED” options are enabled (see Section 7.12 and Section 7.14), the corresponding “Detect” pin will output its “In-Detect” PWM signal. After the key touch is removed, the “Detect” output can be held at the “In-Detect” PWM signal for a time before returning to the “Out of Detect” PWM signal. This allows a reasonable length of time for an LED to be illuminated. The length of this time is controlled by the LED Detect Hold Time. Valid values are in multiples of 16 ms. Default value: 0 (0 ms) Table 7-11. PWM Values Value Meaning 0 0% 1 12.5% 2 25% 3 37.5% 4 50% 5 62.5% 6 75% 7 87.5% 8 100% Table 7-12.
