Description
RO
00h
HW revision: set by the mask set
revision
FW revision: is updated every time
RW
01h
internal firmware of minor revision is
done.
When set, the device controls its own
power mode state machine in no
RW
0h
motion condition. If not set,
POWERDOWN controls the state of
the device (standby/run)
When set, the device sets all internal
variables to optimize the system for
laser illumination.
If set, LASER_OUT is actived to direct
RW
0h
drive a VCSEL, and LASER_NEN
controls its power supply switch.
If not set, LASER_NEN becomes the
LED_ON signal, toggling at frame
rate.
1: The device switches its internal
1.8 V regulator off, and assumes 1.8 V
will be supplied at all times to Vtop,
DVDD and AVDD. VBat can also be
RW
0h
supplied by the same 1.8V or from a
single battery.
0: Device uses internal regulators
(Vtop must be set >= 2.2V).
This bit must be set to 1 to indicate to
RW
0h
the chip that the boot configuration of
the sensor (mainly this register) is
complete, and it can start motioning.
If set to 1, and the chip is set in LED
RW
0h
mode, then the LED is direct driven by
the internal DAC.
If enabled the MCU firmware will go
RW
0h
into an idle mode (I2C commands still
available).
