(Binary Bit 7−0)
Clearing this bit to 0 configures Pin 5 as FAN1 input. Setting this bit to 1 configures
Pin 5 as AIN1. Power−on default = 0.
Clearing this bit to 0 configures Pin 6 as FAN2 input. Setting this bit to 1 configures
Pin 6 as AIN2. Power−on default = 0.
Clearing this bit to 0 configures Pins 17 and 18 to measure V
this bit to 1 configures Pins 17 and 18 as an input for a second remote
temperature−sensing diode. Power−on default = 0.
Clearing this bit to 0 sets the measurement range for the internal V
to 3.3 V. Setting this bit to 1 sets the internal V
Power−on default = 0.
Setting this bit to 1 enables Pin 24 as an active high interrupt input, provided Pins 20
to 24 have been configured as interrupts by setting Bit 7 of the Channel Mode
Register. Power−on default = 0.
Setting this bit to 1 enables Pin 23 as an active high interrupt input, provided Pins 20
to 24 have been configured as interrupts by setting Bit 7 of the Channel Mode
Register. Power−on default = 0.
Setting this bit to 1 enables Pin 22 as an active high interrupt input, provided Pins 20
to 24 have been configured as interrupts by setting Bit 7 of the Channel Mode
Register. Power−on default = 0.
Clearing this bit to 0 configures Pins 20 to 24 as processor voltage ID inputs. Setting
this bit to 1 configures Pins 20 to 24 as interrupt inputs. Power−on default = 0.
