 As an I²C device, the serial clock and serial data lines (SCL and SDA, respectively) need to be pulled up to the logic high voltage level through pull-up resistors. The %%Pmod TMP3%% provides two jumper blocks, JP4, and JP5, that users can individually load to pull the two communication lines (JP4 for SDA and JP5 for SCL) up to a logic high voltage. Jumper JP6 enables a pull-up resistor to be used with the output alert pin. As an I²C device, the serial clock and serial data lines (SCL and SDA, respectively) need to be pulled up to the logic high voltage level through pull-up resistors.

-To read from the %%Pmod TMP3 with its default settings of 9 bits of resolution, users will need to first write to the Pmod TMP3%% the register address of the stored data (0x00). Users may then send a restart condition and perform a read operation from the Pmod, reading in the two bytes of information. The 9-bits of temperature data are arranged in a [[:reference:twos_complement|two's complement]] format, with the first 9 bits in the two bytes consisting of the temperature data and the remaining 7 bits as 0's.+To read from the %%Pmod TMP3 with its default settings of 9 bits of resolution, users will need to first write to the Pmod TMP3%% the register address of the stored data (0x00).
