Since data is transmitted over the 2–wire bus MSB first, temperature data may be written to/read from the
DS1621 as either a single byte (with temperature resolution of 1
°
C) or as two bytes. The second byte
would contain the value of the least significant (0.5
°
C) bit of the temperature reading as shown in Table
1. Note that the remaining 7 bits of this byte are set to all "0"s.
Temperature is represented in the DS1621 in terms of a
°
C LSB, yielding the following 9–bit format:
