TRES Bit Decode
Configuration Register
Configuration Register
bits must be programmed as '0'.
applies to all limits when the temperature is dropping below the threshold so that once the temperature is above a given threshold, it must drop below
the threshold minus the hysteresis in order to be flagged as an interrupt event. Note that hysteresis is also applied to EVENT pin functionality. When
either of the lock bits is set, these bits cannot be altered.
ADDR R/W
Bit 0 - EVENT; Indicates whether the temperature monitor supports interrupt capabilities
Bit 1 - ACC; Indicates the supported temperature accuracy.
Note: Refer to section Resolution Register on page 28.
Bit 2 - RANGE; Indicates the supported temperature range.
The Configuration Register holds the control and status bits of the EVENT pin as well as general hysteresis on all limits.
Bits 15 - 11 – RFU; Reserved for future use. These bits will always read '0' and writing to them will have no affect. For future compatibility, all RFU
Bits 10 - 9 – HYST[1:0]; Control the hysteresis that is applied to all limits as shown in the HYST Bit Decode table that follows. This hysteresis

'0' - The temperature monitor clamps values lower than 0 °C.
'1' (default) - The temperature monitor can read temperatures below 0 °C and sets the sign bit appropriately.
'1' (default) - Bgrade. The temperature monitor has ±1 °C accuracy over the active range (75 °C to 95 °C) and 2°C accuracy over
'0' - The temperature monitor has ±2 °C accuracy of the active range (75 °C to 95 °C) and 3 °C accuracy over the entire operating range.
