Bit Description

4:2

MON_LED_M

ODE

000

R/W

This register controls blinking time of LED in MON

mode.

000: LED always on

001: 80ms PWM active / 80ms off

010: 80ms PWM active / 160ms off

011: 80ms PWM active / 240ms off

100: 80ms PWM active / 320ms off

101: 80ms PWM active / 400ms off

110: 80ms PWM active / 480ms off

111: 80ms PWM active / 560ms off

1:0

MON_ILED

R/W

This register controls the integrated LED driver

current sink of the AS3418 in Monitor operation

mode.

00: ILED current sink switched off

01: 25% duty cycle (4µs on/ 14µs off)

10: 50% duty cycle (9µs on/ 9µs off)

11: 100% duty cycle (18µs on/ 0µs off)

Bit Description

6:5

PBO_LED_M

ODE

R/W

Defines the blinking scheme if PBO mode is active.

Please note that PBO mode has not an individual

LED control register. Therefore this setting uses

hardcoded 25% PWM duty cycle for brightness.

00: LED always off

01: Blinking scheme as in ANC mode

10: Blinking scheme as in MON mode

11: LED always on (=PWM always active)

3:2

ANC_LED_M

ODE

R/W

This register controls the different LED effects for

ANC mode with various on/off times as well as

different flash frequencies.

00: LED always on

01: 80ms on / 1s off

10: 80ms on / 1.5s off
