You can make ASM from C, but C from ASM never. Maybe for 10 years.

Reading of DS1820 or DS18B20 sensor datasheet will help you to understand. With reading you read data, but with writing you send command to sensor to say what you read. Also Sensor have internal alarm, this require writing and configuring data.

0x44 // Issue command CONVERT_T
0xBE // Issue command READ_SCRATCHPAD
