Capacitive Button Matrix (up to 36) and Proximity Controller
with Individual LED Drivers and Buzzer Output

Processing
The first processing step of the raw ticks, coming out of the ASI, is low pass filtering to obtain an estimation of the
average capacitance: tick-ave (see Figure 13).
This slowly varying average is important in the detection of slowly changing environmental changes.

Processing
The difference of the tick average and the raw ticks, tick-diff, is a good estimation of rapid changing input
capacitances.
The tick-diff, tick-ave and the configuration parameters in the SPM are then processed and determines the sensor
information, I2C registers status and PWM control.

Configuration
Figure 14 shows the building blocks used for configuring the SX8663.
Figure 14
Configuration
The default configuration parameters of the SX8663 are stored in the Quick Start Memory (QSM). This
configuration data is setup to a very common application for the SX8663 with 8 buttons. Without any programming
or host interaction the SX8663 will start up in the Quick Start Application.
The QSM settings are fixed and cannot be changed by the user.
