8.5.2.1.5 Read/Write

Bit 8 of the command word is the read/write bit.

Setting this bit to 1 will issue a read command. During a read command the TMP126-Q1 will control the SIO pin after the command word. Setting this bit to 0 will issue a write command. During a write command the controller will control the SIO pin and the TMP126-Q1 will internally set the SIO pin to high impedance.
