This register allows the user to change the resolution of the temperature sensor. The POR default resolution is 0.25°C. The resolution imple-
Legend:
00 = LSB = 0.5°C (register value = 0007)
01 = LSB = 0.25°C (register value = 000F)
10 = LSB = 0.125°C (register value = 0017)
11 = LSB = 0.0625°C (register value = 001F)
Conversion times for each resolution are less than 100ms (worst case).
Bits 0, 1, and 2 are used for test purposes and should only be set to ‘1’.
Functions of bits [0:2]
Bit 0 – gets mapped into bit 0 of capabilities register.
Bit 1 – gets mapped into bit 1 of capabilities register.
Bit 2 – gets mapped into bit 2 of capabilities register.

Resolution bits 4-3 TRES[4:3]
The Manufacturer ID Register holds the PCI SIG number assigned to the specific manufacturer.
The upper byte of the Device ID / Revision Register stores a unique number indicating the TSE2002B3C from other devices.
The lower byte holds the revision value.
