6 / 17 page TMP122-EP SBOS454 – NOVEMBER 2008 .......................................................................................................................................................................................... www.ti.com Multiple commands may be strung together as illustrated in Figure 2. The TMP122 accepts commands alternating with 16-bit response data. On lowering CS, the part always responds with a READ from the address location indicated by the READ address register. If the next command is a READ command then data is returned from the address specified by the READ command with the 16th clock resetting the READ address register to the default temperature register. The TMP122 then expects a 16-bit command. If the command is a WRITE command, then the 16 clocks following the command will again return temperature data. Figure 3, Figure 4, Figure 5, and Figure 6 detail the communication sequences. Table 1.
