ALERT
R/W
*
Read/Write
Description
ALERT = 1, Pin 5 (PWM2/
SMBALERT
) is configured as an
SMBALERT
interrupt
output to indicate out-of-limit error conditions.
THERM
Timer = 1 enables
THERM
monitoring functionality on Pin 9 when it is
configured as
THERM
. When
THERM
is asserted, fans can be run at full speed (if the
BOOST bit is set) or a timer can be triggered to time how long
THERM
has been asserted for.
BOOST = 1, assertion of
THERM
will cause all fans to run at 100% duty cycle for
fail-safe cooling.
FAST = 1 enables fast TACH measurements on all channels. This increases the
TACH measurement rate from once per second, to once every 250 ms (4 ).
DC1 = 1 enables TACH measurements to be continuously made on TACH1.
DC2 = 2 enables TACH measurements to be continuously made on TACH2.
DC3 = 1 enables TACH measurements to be continuously made on TACH3.
DC4 = 1 enables TACH measurements to be continuously made on TACH4.

This register becomes read-only when the Configuration Register 1 Lock bit is set to 1. Any further attempts to write to this register will have no effect.
Table XXXVI. Register 0x79 –
THERM
Status Register (Power-On Default = 0x00)
R/W
Description
Read Only
Times how long
THERM
input is asserted. These seven bits will read zero until the
THERM
assertion time exceeds 45.52 ms.
ASRT/TMR0
Read Only
Gets set high on the assertion of the
THERM
input. Cleared on read. If the
THERM
assertion time exceeds 45.52 ms, this bit gets set and becomes the LSB of the 8-bit TMR
reading. This allows
THERM
assertion times from 45.52 ms to 5.82 s to be reported
back with a resolution of 22.76 ms.

Table XXXVII. Register 0x7A –
THERM
Limit Register (Power-On Default = 0x00)
R/W
Description
Read/Write
Sets maximum
THERM
assertion length allowed before an interrupt is generated. This
is an 8-bit limit with a resolution of 22.76 ms allowing
THERM
assertion limits of 45.52 ms
to 5.82 s to be programmed. If the
THERM
assertion time exceeds this limit, Bit 5 (F4P)
of Interrupt Status Register 2 (Reg.0x42) will be set. If the limit value is 0x00, then an
interrupt will be generated immediately on the assertion of the
THERM
input.
