LED Behavior Registers
The LED Behavior registers control the operation of LEDs. Each LEDx / GPIOx pin is controlled by a
2-bit field. If the LEDx / GPIOx pin is configured as an input, then these bits are ignored.
If the corresponding LED output is linked to a Capacitive Touch Sensor than the Start and Stop triggers
are used. The defined behavior will activate when the Start Trigger is met and will stop when the Stop
Trigger is met. See Table 5.50 and note the behavior of the Breathe Hold and Pulse Release option.
If the LED output is not associated with a a Capacitive Touch Sensor, then two available options are
Direct and Breathe. In this case, the Start and Stop triggers are ignored and the output of the LED is
activated exclusively by the bit state of the control signals.

5.34.3
LED Behavior 3 - 83h
Bits 7 - 6 - LED11_ALT[1:0] - Determines the behavior of LED 11 when the PWR_LED bit is set and
either the SLEEP or DSLEEP bits are set (see Section 5.1).
Bits 5 - 4 - LED11_CTL[1:0] - Determines the behavior of LED11 when the PWR_LED bit is set and
both the SLEEP and DSLEEP bits are not set (see Section 5.1).
