NOTES:
1. Bit 3 of Configuration register 1 must be set to 0 (default value is 0)
2. Writing to RESERVED bits may cause unexpected results. RESERVED bits that must be correctly
2. Writing to RESERVED bits may cause unexpected results. RESERVED bits that must be correctly
programmed are identified in the register definitions in the following section. Reading from RESERVED bits
will return unknown values.
will return unknown values.
3. The 4 least significant bits of the thermal sensor die revision code may change and should not be used for
identification
4. Ch. 1 limit registers have a separate 7-bit read and write address while channel 2 limit registers have the
same 7-bit address for read and write.
All of the commands in
are for reading or writing registers in the SMBus thermal
sensor, except the one-shot register (0Fh). The one-shot command forces the start of a new
conversion cycle. If a conversion is in progress when the one-shot command is received, then the
command is ignored. If the thermal sensor is in stand-by mode when the one-shot command is
received, a conversion is performed and the sensor returns to stand-by mode. The one-shot
command is not supported when the thermal sensor is in auto-convert mode.
