Manufacturer's ID always defaults to 0000 0001; this register is writable and can be reset to the default value by the

INITIALIZATION bit in the Configuration Register (address 00h, bit 7).

3Fh

Stepping/Die Revision ID always defaults to 0000 1000; this register is writable and can be reset to the default

value by the INITIALIZATION bit in the Configuration Register.

(1)

Setting all ones to the high limits for voltages and fans (0111 1111 binary for temperature) means interrupts will never be generated

except the case when voltages go below the low limits.

For voltage input high limits, the device is doing a greater than comparison. For low limits, however, it is doing a less than or equal to

comparison.
