7.5.4.1 Writes

To write on the I2C bus, the controller sends a START condition on the bus with the address of the target, as well as the last bit (the R/W bit) set to 0b, which signifies a write. The target acknowledges, letting the controller know the target is ready. After this operation, the controller starts sending the register pointer and data to the target, and the controller terminates the transmission with a STOP condition.

Writes to read-only registers or register locations outside of the register map are ignored. The TMP113 still performs and acknowledges when writing outside of the register map. Figure 7-7 shows an example of writing a single word write communication.
