Table XXXV. Register 0x78 – Configuration Register 3 (Power-On Default = 0x00)  
Bit  
Name  
R/W*  
Description  
<0>  
ALERT  
Read/Write  
ALERT = 1, Pin 5 (PWM2/SMBALERT) is configured as an SMBALERT interrupt  
output to indicate out-of-limit error conditions.  
<1>  
THERM  
Read/Write  
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.  
<2>  
<3>  
BOOST  
FAST  
Read/Write  
Read/Write  
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
؋
).  
<4>  
<5>  
<6>  
<7>  
DC1  
DC2  
DC3  
DC4  
Read/Write  
Read/Write  
Read/Write  
Read/Write  
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)  
Bit  
Name  
R/W  
Description  
<7:1>  
TMR  
Read Only  
Times how long THERM input is asserted. These seven bits will read zero until the  
THERM assertion time exceeds 45.52 ms.  
<0>  
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)  
Bit  
Name  
R/W  
Description  
<7:0>  
LIMT  
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.
