SBOS473I March 2009 – December 2018 TMP112
The extended mode bit configures the device for normal mode operation (EM = 0) or extended mode operation (EM = 1). In normal mode, the temperature register and the high and low limit registers use a 12-bit data format. Normal mode is used to make the TMP112 family compatible with the TMP75 device.
Extended mode (EM = 1) allows measurement of temperatures above 128°C by configuring the temperature register and the high and low limit registers for 13-bit data format.
