Description

VCSEL_clk_div2: If set, operates the VCSEL clock at

half frequency - see section 5.7 - 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)

cmd_data5 = 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

– see cmd_data4

4 - Output low (default after startup)

5 - Output high

6:15 - Reserved, do not use
