A one places the LM87 in a lower power "Shutdown" mode.
A one enables the input as AIN1, a zero enables the input as FAN1.
A one enables the input as AIN2, a zero enables the input as FAN2.
A one enables the 2.5V, V
A one configures the LM87 for 5.0V V

A one enables pin 24 as an active low interrupt input. Bit 7 must also be set to
configure the VID/IRQ inputs to IRQ mode.
A one enables pin 23 as an active low interrupt input. Bit 7 must also be set to
configure the VID/IRQ inputs to IRQ mode.
A one enables pin 22 as an active low interrupt input. Bit 7 must also be set to
configure the VID/IRQ inputs to IRQ mode.
A one configures the VID/IRQ inputs as Interrupt Inputs. A zero configures the VID/IRQ
inputs as VID inputs only.
