6.2.2 Capability Register (16-bit Read-only, Address = 00h)
This register is a 16-bit read-only register used to specify the functional capabilities of the temperature sensor.
The AT30TSE004A is capable of measuring temperature with ±1C over the active range and ±2C over the
monitor range. The Capability Register functions are described in Table 6-3 and Table 6-4.

7 EVSD
Event Output Status During Shutdown Mode:
1 = The
EVENT pin output is deasserted (not driven) when entering Shutdown Mode and will
remain deasserted upon exit from Shutdown Mode until the next temperature measurement
sample is taken. In Interrupt Mode, the
EVENT pin maybe asserted when existing Shutdown if
a pending Interrupt has not be cleared.
6 TMOUT
Timeout:
1 = BusTimeout supported within the range 25 to 35ms.

2 RANGE 1 = Can read temperatures below 0°C and sets appropriate sign bit.
1 SACC
Supported Accuracy:
1 = Supports a B-grade accuracy of ±1C over the active range (75C to 95C) and 2C over the
monitor range (40C to 125C).
0 ICAP
Interrupt Capability:
1 = Supports Interrupt capabilities.
