7.5.2 General-Call Reset

The TMP461-EP device supports reset using the two-wire general-call address 00h (0000 0000b). The TMP461-EP device acknowledges the general-call address and responds to the second byte. If the second byte is 06h (0000 0110b), the TMP461-EP device executes a software reset. This software reset restores the power-on reset state to all TMP461-EP registers and aborts any conversion in progress. The TMP461-EP device takes no action in response to other values in the second byte.
