TMF8701 − Register Description

0x03

Set flag to perform distance or proximity measurement

with 7 bytes of data containing where

cmd_data6 = Bit mask which algorithm is used

Bit 0 - When 1 proximity is enabled

Bit 1 - When 1 distance enabled

Bits 3:2 - Reserved; set to 00b.

Bits 4 - algImmediateInterrupt – When 1 proximity and

distance 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 proximity (and distance if

enabled) was finished

Bit 5 - When 1 combine the capture of the proximity and

distance algorithms for maximum speed

Bit 6 - Reserved; set to 0.

Bit 7 - When 1 do not go to standby between

measurements (faster measurement times but higher

current consumption)

Please note if bits 0 and 1 are both zero, the system will

default to proximity and distance algorithms enabled.

cmd_data5 = Bits for GPIO control

Bits 3:0 - GPIO0 settings

0 – Disabled (tristate)

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 - see

cmd_data4

4 - Output low (default after startup)

5 - Output high

6:15 – Reserved, do not use

Bits 7:4 - GPIO1 settings

0 - Disabled (tristate)

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 – see

cmd_data4

4 - Output low (default after startup)

5 - Output high

6:15 – Reserved, do not use
