Figure 10. Filter Curves were Purposely Offset for Clarity

Figure 10 shows the filter in use in a typical Intel processor on a 65/90 nm process system. Note that the two

curves have been purposely offset for clarity. Inserting the filter does not induce an offset as shown.

FAULT QUEUE

The LM96063 incorporates a Fault Queue to suppress erroneous ALERT triggering. The Fault Queue prevents

false triggering by requiring three consecutive out-of-limit HIGH or LOW temperature readings. See Figure 11.

The Fault Queue defaults to OFF upon power-up and may be activated by setting the RDTS Fault Queue bit in

the Configuration Register to a 1.

ONE-SHOT REGISTER

The One-Shot Register is used to initiate a single conversion and comparison cycle when the device is in

standby mode, after which the data returns to standby. This is not a data register. A write operation causes the

one-shot conversion. The data written to this address is irrelevant and is not stored. A zero will always be read

from this register.

SERIAL INTERFACE RESET

In the event that the SMBus Master is reset while the LM96063 is transmitting on the SMBDAT line, the

LM96063 must be returned to a known state in the communication protocol. This may be done in one of two

ways:

1. When SMBDAT is Low, the LM96063 SMBus state machine resets to the SMBus idle state if either SMBDAT

or SMBCLK are held Low for more than 35 ms (tTIMEOUT). Devices are to timeout when either the SMBCLK or
