Multiple Channel Capacitive Touch Sensor and LED Driver
Datasheet
Bits 2 - 0 - FALL_RATE[2:0] - Determines the falling edge time of an LED when it transitions from its
maximum drive state to its minimum drive state as shown in Table 5.69.

The LED Off Delay register determines the amount of time an LED In direct mode remains active after
it is no longer actuated (such as after a release has been detected or the drive state has been
changed). This register is only used if the LED is linked to a Capacitive Touch sensor.
Bits 2 - 0 - DIR_OFF_DLY[2:0] - Determines the turn-off delay for all LEDs that are configured to
operate in Direct Mode as shown in Table 5.71.
