Capability register (read-only)
This 16-bit register is read-only, and provides the TS capabilities which comply with the
minimum JEDEC JC 42.4 specifications (see
STTS424E02 provides temperatures at 0.25 resolution (10-bit).
Alarm window trip
The device provides a comparison window with an upper temperature trip point in the alarm
upper boundary register, and a lower trip point in the alarm lower boundary register. When
enabled, the event output will be triggered whenever entering or exiting (crossing above or
below) the alarm window.
Critical trip
The device can be programmed in such a way that the event output is only triggered when
the temperature exceeds the critical trip point. The critical temperature setting is
programmed in the critical temperature register. When the temperature sensor reaches the
critical temperature value in this register, the device is automatically placed in comparator
mode, which means that the critical event output cannot be cleared by using software to set
the clear event bit.
