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.

1

FAN2/AIN2

R/

W

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.

2

configures Pins 18 and 19 as an input for a second remote temperature-sensing diode. Power-on

default = 0.
