eKT2101
Capacitive Touch Sensor Controller
Changing I2C slave address by setting bit7~bit1 of Register Number 7
Fig. 4-2-3 shows the system block diagram including I2C slave interface. The
eKT2101 detects the object on the touch pad sensor and sends the information
including button state to host. In I2C slave interface, the IFSEL0/SCL/SCK and
IFSEL1SDA/SDI signals should be pulled high with 5.1k resistors at the end of the
host. Besides, the IFSEL2/SDO signal should be connected to ground to be pulled low
at the end of the host. The host processor has to provide the I2C serial clock signal
(SCL) to eKT2101.
Figure 4-2-3 System block diagram with I2C Interface
An address packet consisting of a slave address and a READ or a WRITE bit is called
Slave address+R or Slave address+W, respectively. The sequence of events required
to write data to the touchpad controller is shown next.
