Setting this bit to 1 enables the GPIOs. Default = 0.
1 = SCL timeout enabled. 0 = SCL timeout disabled = default.
1 = SDA timeout enabled. 0 = SDA timeout disabled = default.
This bit sets the digital threshold for the VID digital inputs. 0 =default. 1 = low thresholds
selected = 0.65 V.
This bit sets the digital threshold for the THERM digital inputs. 0 =default. 1 = low thresholds
selected = 2/3 V
Setting this bit to 1 resets the chassis intrusion circuit. This bit clears itself. Default = 0.
Setting this bit to 1 enables the XOR tree test. Default = 0.
Setting this bit to 1 enables V_core_low. Default = 0.
Setting this bit to 1 enables the TACH1 measurement. Default = 0.
Setting this bit to 1 enables the TACH2 measurement. Default = 0.
Setting this bit to 1 enables the TACH3 measurement. Default = 0.
Setting this bit to 1 enables the TACH4 measurement. Default = 0.
Setting this bit to 1 enables the TACH5 measurement. Default = 0.
Setting this bit to 1 enables the TACH6 measurement. Default = 0.
Setting this bit to 1 enables the TACH7 measurement. Default = 0.
Setting this bit to 1 enables the TACH8 measurement. Default = 0.
Setting this bit to 1 enables continuous measurements on TACH1 and TACH5 in low frequency
PWM mode. Continuous measurement means that pulse stretching is turned off and the PWM
output and TACH inputs are no longer synchronized. Default = 1.
Setting this bit to 1 enables continuous measurements on TACH2 and TACH6 in low frequency
PWM mode. Continuous measurement means that pulse stretching is turned off and the PWM
output and TACH inputs are no longer synchronized. Default = 1.
Setting this bit to 1 enables continuous measurements on TACH3 and TACH7 in low frequency
PWM mode. Continuous measurement means that pulse stretching is turned off and the PWM
output and TACH inputs are no longer synchronized. Default = 1.
Setting this bit to 1 enables continuous measurements on TACH4 and TACH8 in low frequency
PWM mode. Continuous measurement means that pulse stretching is turned off and the PWM
output and TACH inputs are no longer synchronized. Default = 1.
