7. CONTENT OF DATA REGISTERS
7.1 Configuration Register  Index 40h
Power on default [7:0] = 0000, 0001 b
BIT
NAME
READ/WRITE
DESCRIPTION
7 INITIALIZATION Read/Write
A one restores power on default value to all registers
except the Serial Bus Address register. This bit clears
itself since the power on default is zero.
6-5 Reserved
Read/Write
Reserved
4 SOFT_PWDN Read/Write
Software Power Down. If set to 1 to power down this
chip, but I2C interface is still working.
3 EN_T2_FAULT Read/Write
Enable Temperature 2 Fault Function. When
temperature 2 is out of the Temperature Fault Limit
value (defined Index 54), the Pin 11 will go to low level.
This function is wire-or with temperature 1 fault if
temperature 1 fault function is enable.
2 EN_T1_FAULT Read/Write
Enable Temperature 1 Fault Function. When
temperature 1 is out of the Temperature Fault Limit
value (defined Index 53), the Pin 11 will go to low level.
This function is wire-or with temperature 2 fault if
temperature 2 fault function is enable.
1 INT_ CLEAR
Read/Write
A one disables the SMI# outputs without affecting the
contents of Interrupt Status Registers. The device will
stop monitoring. It will resume upon clearing of this bit.
0 START
Read/Write
A one enables startup of monitoring operations, a zero
puts the part in standby mode.
Note: The outputs of Interrupt pins will not be cleared
if the user writes a zero to this location after an
interrupt has occurred unlike "INT_Clear'' bit.
7.2 SMI# Status Register 1  Index 41h
Power on default [7:0] = 0000, 0000 b
BIT
NAME
READ/WRITE
DESCRIPTION
7 TEMP2
Read Only
A one indicates a High or Low limit has been exceeded from
temperature sensor 2. (CPUT2/PII2)
6 TEMP1
Read Only
A one indicates a High or Low limit has been exceeded from
temperature sensor 1. (CPUT1/PII1)
5 FAN2
Read Only
A one indicates the fan count limit has been exceeded.
4 FAN1
Read Only
A one indicates the fan count limit has been exceeded.
3 VCC
Read Only
A one indicates a High or Low limit has been exceeded.
( VCC, +3.3V)
