Enables the THERM1 timer circuit. Default = 0.
Setting the bit to 1 means that the THERM1 pin is asserted low as an output whenever the
local temperature exceeds the local THERM1 temperature limit. Default = 0.
Setting the bit to 1 means that the THERM1 pin is asserted low as an output whenever the
Remote 1 temperature exceeds the Remote 1 THERM1 temperature limit. Default = 0.
Setting the bit to 1 means that the THERM1 pin is asserted low as an output whenever the
Remote 2 temperature exceeds the Remote 2 THERM1 temperature limit. Default = 0.
Setting the bit to 1 means that the THERM1 pin is asserted low as an output whenever the
Remote 3 temperature exceeds the Remote 3 THERM1 temperature limit. Default = 0.
Reserved for future use.
Enables the THERM2 timer circuit. Default = 0.
Setting the bit to 1 means that the THERM2 pin is asserted low as an output whenever the
local temperature exceeds the local THERM2 temperature limit. Default = 0.
Setting the bit to 1 means that the THERM2 pin is asserted low as an output whenever the
Remote 1 temperature exceeds the Remote 1 THERM2 temperature limit. Default = 0.
Setting the bit to 1 means that the THERM2 pin is asserted low as an output whenever the
Remote 2 temperature exceeds the Remote 2 THERM2 temperature limit. Default = 0.
Setting the bit to 1 means that the THERM2 pin is asserted low as an output whenever the
Remote 3 temperature exceeds the Remote 3 THERM2 temperature limit. Default = 0.
Reserved for future use.
0 = +12V1; 1 = TACH5 input. Default =1.
0 = GPIO4; 1= TACH4 input (that is, if the VIDs are not selected). Default = 1.
0 = GPIO3; 1= TACH3 input (that is, if the VIDs are not selected). Default = 1.
0 = GPIO2; 1= TACH2 input (that is, if the VIDs are not selected). Default = 1.
0 = GPIO1; 1= TACH1 input (that is, if the VIDs are not selected). Default = 1.
1 enables the D3+ and D3− inputs on Pin 19 and Pin 20. 0 enables the voltage measurement
input and SCSI_TERM2 input. Default = 1.
1 enables the D1+ and D1− inputs on Pin 15 and Pin 16. 0 enables the voltage measurement
input and SCSI_TERM1 input. Default = 1.
Setting this bit to 1 enables the VIDs on Pin 1 to Pin 4, Pin 28, Pin 31, and Pin 32. Default = 0.
