Description
Reserved for future use; can not be written; should be ignored; will typically read as 0
0: Configuration register bit 4 is frozen upon setting Configuration register bit 8 (i.e. a TS shut-
down freezes the E¯¯V¯E¯N¯T¯ output)
1: Configuration register bit 4 is cleared upon setting Configuration register bit 8 (i.e. a TS
shut-down de-asserts the E¯¯V¯E¯N¯T¯ output)
0: The TS implements SMBus time-out within the range 10 to 60 ms
1: The TS implements SMBus time-out within the range 25 to 35 ms
00: LSB = 0.50°C (9 bit resolution)
01: LSB = 0.25°C (10 bit)
10: LSB = 0.125°C (11 bit)
11: LSB = 0.0625°C (12 bit)
0: Positive Temperature Only
1: Positive and Negative Temperature
0: ±2°C over the active range and ±3°C over the operating range (Class C)
1: ±1°C over the active range and ±2°C over the monitor range (Class B)
0: Critical Temperature only
1: Alarm and Critical Temperature
Notes:
(1) Configuration Register bit 4 can be cleared (but not set) after Configuration Register bit 8 is set, by writing a “1” to Configuration Register
bit 5 (i.e. the E¯¯V¯E¯N¯T¯ output can be de-asserted during TS shut-down periods)
