Rst

Type

Description

7:0

command

Direct the device to control or select contents of the registers from

0x20...0xDF

Setting

Meaning

0x00

No command

0x02

Set flag to perform target distance measurement with 8 bytes of data

containing where including setting of calibration (and algorithm state)

configuration.

cmd_data7 = Bit mask which calibration/state data was downloaded

from the host to TMF8801 prior to setting this command:

Bits

Definition

dataFactoryCal: When 1 data from register 0x20 onward

includes factory calibration

dataAlgState: If set, also set dataFactoryCal=1. Data from

algorithm state.

cmd_data6… cmd_data0: Identical to command=0x03.

0x03

Set flag to perform target distance measurement with 7 bytes of data

containing where

cmd_data6 = Bit mask which algorithm is used

Bits

Definition

Set to ‘1’

VCSEL_clk_div2: If set, operates the VCSEL clock at half

frequency - see section 7.7 - and doubles the ranging active time

where the VCSEL is enabled. It is recommended to use together

with spread_spectrum_mode=1.

Reserved; set to 0b.

algImmediateInterrupt

– When 1 target distance measurement

will immediately report to the host an interrupt of the capturing

caused by a GPIO event; when 0, will only report to the host

when target distance measurement was finished

When 1 combine the capture of the short and long distance

histogram for maximum speed

Reserved; set to 0.

When 1 do not go to standby between measurements (faster

measurement times but higher current consumption)
