Description
0
Start
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.
At start up, limit checking functions and scanning begin. Note, all limits should be set
in the Value RAM before setting this bit HIGH.
A one enables the INT Interrupt output.

INT_Clear
Read/Write
Read/Write
Read/Write
A one disables the INT output without affecting the contents of Interrupt Status
Registers. The device will stop monitoring. It will resume upon clearing of this bit.
A one outputs at least a 20 ms active low reset signal at RESET. This bit is cleared
once the pulse has gone inactive.

CI_Clear
Read/Write
Read/Write
A one outputs a minimum 20 ms active low pulse on the CI pin. The register bit self
clears after the pulse has been output. This bit is mirrored in the CI Clear Register bit
7.
A one restores power on default value to the Configuration Register, Interrupt Status
Registers, Interrupt Mask Registers, CI Clear Register, VID/Fan Divisor Register,
VID4, Temperature Configuration Register, and the Extended Mode Registers. This bit
clears itself since the power on default is zero.
