DATASHEET
The Sensor Base Count registers store the calibrated “Not Touched” input value from the Capacitive
Touch Sensor inputs. These registers are periodically updated by the re-calibration routine.
The routine uses an internal adder to add the current count value for each reading to the sum of the
previous readings until sample size has been reached. At this point, the upper 16 bits are taken and
used as the Sensor Base Count. The internal adder is then reset and the re-calibration routine
continues.
The data presented is determined by the C_DSP bits (see Section 5.12).

LED / GPIO Direction Registers
The LED / GPIO Direction registers control the data flow direction for the LED / GPIO pins. Each pin
is controlled by a single bit.
Bit 7 - LED8_DIR - Controls the direction of the LED8 / GPIO8 pin.
‘0’ (default) - The LED8 / GPIO8 pin is configured as an input and cannot be used to drive an LED.
‘1’ - The LED8 / GPIO8 pin is configured as an output.
Bit 6 - LED7_DIR - Controls the direction of the LED7 / GPIO7 pin.
Bit 5 - LED6_DIR - Controls the direction of the LED6 / GPIO6 pin.
Bit 4 - LED5_DIR - Controls the direction of the LED5 / GPIO5 pin.
Bit 3 - LED4_DIR - Controls the direction of the LED4 / GPIO4 pin.
Bit 2 - LED3_DIR - Controls the direction of the LED3 / GPIO3 pin.
Bit 1 - LED2_DIR - Controls the direction of the LED2 / GPIO2 pin.
Bit 0 - LED1_DIR - Controls the direction of the LED1 / GPIO1 pin.
