Start
R/W
'1' enables startup of monitoring activity; '0' puts device in shutdown mode.
1
INT Enable
R/W
'1' enables the INT output.
2
INT Polarity Select
R/W
'1' selects active-high, open-source output; '0' selects active-low, open-drain output.
'1' disables the INT output without affecting the contents of the Interrupt Status Registers.
3
INT_Clear
R/W
The device stops monitoring and resumes on a '0'.
'1' outputs an active-low reset signal at RST_OUT, if bit 7 and bit 6 in the Fan Divisor/

Register (address 05h) are set to '1' and '0', respectively. This bit is cleared when the pulse
becomes inactive.
5
Chassis Clear
R/W
'1' clears the GPI/CI pin. This bit clears itself after 10ms.
6
