Manufacturer ID Register
Manufacturer ID Register
The Manufacturer ID Register holds the PCI SIG number assigned to the specific manufacturer.
Device ID/Revision Register
Device ID/Revision Register
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.
Resolution Register
This register allows the user to change the resolution of the temperature sensor. The POR default resolution is 0.25癈. The resolution imple-
mented via this register is also reflected in the capability register.
Resolution Register
Legend:
Resolution bits 4-3 TRES[4:3]
00 = LSB = 0.5癈 (register value = 0007)
01 = LSB = 0.25癈 (register value = 000F)
10 = LSB = 0.125癈 (register value = 0017)
11 = LSB = 0.0625癈 (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.
