What command follows after initiating the onewire exchange process?

Question

Arduino

I'm trying to figure out the sequence of actions on the onewire bus.
There is a DS18S20 sensor.
1. When initiating, first the Arduino sets 0 for 480µs, and then through the rise of the pulse, the DS18S20 itself pulls 480µs to 0.
2. Arduino must send a command, but I can’t figure out which one is 0xF0, 0x33, 0x55 or 0xCC.

I have two sensors on the line.
As I understand correctly:
RESET in response to PRESENCE, 0xF0 all devices begin to exchange addresses with Arduino.
Or misunderstood something?
