Sensor LED Linking Registers
The Sensor LED Linking registers control whether a Capacitive Touch Sensor is linked to an LED
output or not. If the corresponding bit is set, then the appropriate LED output will change states defined
by the LED Behavior controls (see Section 5.34) in response to the Capacitive Touch sensor.
If the LED channel is configured as an input, then the corresponding Sensor LED Linking bit is ignored.
Bit 7 - UP_DOWN_LINK - Links the LED10 output to a detected UP condition on the group including
a slide in the “up” direction, a tap on the “up” side of the group or a press and hold condition on the
“up” side of the group. The LED10 driver will be actuated and will behave as determined by the
LED10_CTL bits. This bit also links the LED9 output to a detected DOWN condition on the group
including a slide in the “down” direction, a tap on the “down” side of the group or a press and hold
condition on the “down” side of the group. The LED9 driver will be actuated and will behave as
determined by the LED9_CTL bits.
LED9 and LED10 will not be active simultaneously. If LED9 is actuated by detecting a slide, tap, or
press and hold event, LED10 will be inactive. Likewise, if LED10 is actuated by detecting a slide, tap,
or press and hold event, LED9 will be inactive.
Bit 6 - CS7_LED7 - Links the LED7 output to a detected touch on the CS7 sensor. When a touch is
detected, the LED is actuated and will behave as determined by the LED Behavior controls.
‘0’ - The LED7 output is not associated with a the CS7 input. If a touch is detected on the CS7
input, then the LED will not automatically be actuated. The LED is enabled and controlled via the
LED Output Configuration register (see Section 5.31) and the LED Behavior registers (see
‘1’ - The LED 7 output is associated with the CS7 in put. If a touch is detected on the CS7 input
then the LED will be actuated and behave as defined in Table 5.50. Furthermore, the LED will
automatically be enabled.
Bit 5 - CS6_LED6 - Links the LED6 output to a detected touch on the CS6 sensor. When a touch is
detected, the LED is actuated and will behave as determined by the LED Behavior controls.
Bit 4 - CS5_LED5 - Links the LED5 output to a detected touch on the CS5 sensor. When a touch is
detected, the LED is actuated and will behave as determined by the LED Behavior controls.
Bit 4 - CS4_LED4 - Links the LED4 output to a detected touch on the CS4 sensor. When a touch is
detected, the LED is actuated and will behave as determined by the LED Behavior controls.
Bit 2 - CS3_LED3 - Links the LED3 output to a detected touch on the CS3 sensor. When a touch is
detected, the LED is actuated and will behave as determined by the LED Behavior controls.
Bit 1 - CS2_LED2 - Links the LED2 output to a detected touch on the CS2 sensor. When a touch is
detected, the LED is actuated and will behave as determined by the LED Behavior controls.
Bit 0 - CS1_LED1 - Links the LED1 output to a detected touch on the CS1 sensor. When a touch is
detected, the LED is actuated and will behave as determined by the LED Behavior controls.
