ANALOG_CTRL2

led_out_dmib_ctrl

PRW

Select the source of LED

out.

0 = Automatic (by DMIB

controller)

1 = Direct ctrl (by

led_out_manual)

led_out_manual

PRW

If led_out_dmib_ctrl is low,

LED driver enable control.

0 = LED driver disable

(direct ctrl)

1 = LED driver enable (direct

ctrl)

dmib_dac_avdd_sel

3:2

PRW

AVDD select for DMIB DAC

0 = AVDD1V5 = 1v45

1 = AVDD1V5 = 1v5

2 = AVDD1V5 = 1v55

3 = AVDD1V5 = 1v6

led_dac_control

6:4

PRW

Adjust LED Drive DAC drive

output current.

0 = Iout = 0 mA

1 = Iout = 2 mA

2 = Iout = 4 mA

3 = Iout = 6 mA

4 = Iout = 8 mA

5 = Iout = 10 mA

6 = Iout = 12 mA

7 = Iout = 14 mA

led_out_polarity

PRW

LED_OUT_EN polarity

0 = High when LED must be

ON (= dmib_led_on)

1 = Low when LED must be

ON (= !dmib_led_on)

CLOCKS_LO

clk_motion_timer

PRW

Timer clock enabled (forced

always on).

clk_framedump_en

PRW

Framedump clock enabled

(forced always on).

RESETS

framedump_reset_n

PRW

Framedump reset signal

(active low)

CONTROL

motion_engine_start

PRW

Timer interrupt enable. This

enables the motion timer to

operate. Motion timer

generates pulses that trigger

frame capture and motion

processing.
