Reading (MSB)
This is the MSB of the 2’s complement value, representing the
temperature of the remote diode connected to the LM63. Bit 7 is the sign
bit, bit 6 has a weight of 0x40 (64), and bit 0 has a weight of 1C. This
byte to be read first.
This is the LSB of the 2’s complement value, representing the
temperature of the remote diode connected to the LM63. Bit 7 has a
weight 0.5C, bit 6 has a weight of 0.25C, and bit 5 has a weight of
0.125C.
Always 00.

OFFSET (MSB)
These registers contain the value added to or subtracted from the
remote diode’s reading to compensate for the different non-ideality
factors of different processors, diodes, etc. The 2’s complement value, in
these registers is added to the output of the LM63’s ADC to form the
temperature reading contained in registers 01 and 10.

This 8-bit integer storing the T_CRIT limit is nominally 85C. This value
can be changed
once
after power-up by setting T_CRIT Limit Override
(bit 1) in the Configuration register to a 1, then programming a new
T_CRIT value into this register. The T_CRIT Limit can not be changed
again except by cycling power to the LM63.
8-bit integer storing T_CRIT hysteresis. T_CRIT stays activated until the
remote diode temperature goes below [(T_CRIT Limit)—(T_CRIT
Hysteresis)].
These bits are unused and should always set to 0.
00: Filter Disabled
01: Filter Level 1 (minimal filtering, same as 10)
10: Filter Level 1 (minimal filtering, same as 01)
11: Filter Level 2 (maximum filtering)
0: the ALERT/Tach pin functions normally.
1: the ALERTTach pin behaves as a comparator, asserting itself when
an ALERT condition exists, de-asserting itself when the ALERT condition
goes away.
