Functional Description
4.5 Register 3Eh: Company ID
The company ID register contains the company identification number. For National Semiconductor this is 01h. This number is
assigned by Intel and is a method for uniquely identifying the part manufacturer. This register is read only — a write to this
register has no effect.
4.6 Register 3Fh: Version/Stepping
The four least significant bits of the Version/Stepping register [3.0] contain the current stepping of the LM96000 silicon. The four
most significant bits [7.4] reflect the LM96000 base device number when set to a value of 0110b. For the LM96000, this register
will read 01101000b (68h). Bit 3 of the stepping field is set to indicate that the LM96000 is a super-set of the LM85 family of
products.
The register is used by application software to identify which device in the hardware monitor family of ASICs has been
implemented in the given system. Based on this information, software can determine which registers to read from and write to.
Further, application software may use the current stepping to implement work-arounds for bugs found in a specific silicon
stepping.
This register is read only — a write to this register has no effect.
