COMMAND

Field

Name

Rst

Type

Description

cmd_data2 = low_threshold 8-bit MSB value

cmd_data1 = high_threshold 8-bit LSB value

cmd_data0 = high_threshold 8-bit MSB value

0x09

Read additional configuration for application

– only available for

firmware version 3.0.22 or higher

After the command is executed, the persistence, low_threshold

and high_threshold are stored in registers 0x20 to 0x24

– see

section 6.7 Interrupt suppression registers

– result of command

= 0x09

0x0A

Perform factory calibration in the final customer application

including cover glass, no ambient light and no target.

The result from the factory calibration is stored from register

0x20 onwards (14 bytes).

0x0B

Set flag to download calibration (and algorithm state)

configuration to TMF8805

cmd_data0 = Bit mask which calibration/state data was

downloaded from the host to TMF8805 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 register 0x20 onwards includes factory calibration

and algorithm state.

0x0F

Set gpio control setting without actually performing a

measurement as commands 0x02 or 0x03 would do:

cmd_data0 = Bits for GPIO control

3:0

GPIO0 settings

0 - Input

1 - Input: Active low disables collection, immediately

abandoning current measurement. Returning to high

restarts new measurement

2 - Input: Active high disables collection, immediately

abandoning current measurement. Returning to low

restarts new measurement

3 - Output: VCSEL pulse output

4 - Output low

5 - Output high

6:15 - Reserved, do not use

7:4

GPIO1 settings

0 - Input
