Revision1.1
8.5.18 FANPWM2 Current Duty
Current FANPWM2 duty cycle.
Location: 31h
Type:
R/W or RO (Becomes read-only when FANPWM2 Configuration is not set for manual mode.)
8.5.19 FANPWM3 Current Duty
Current FANPWM3 duty cycle.
Location: 32h
Type:
R/W or RO (Becomes read-only when FANPWM3 Configuration is not set for manual mode.)
8.5.20 Company ID
Company identification number.
Location: 3Eh
Type:
RO
Bit
Description
7-0
PWM_DUTY. Holds the current value of the duty cycle of the associated FANPWM signal. The behavior of this
field depends on the FANPWM Control Configuration register:
• In Manual mode, PWM_DUTY field is R/W: the value written selects the duty cycle of the FANPWM output.
• In all other modes, PWM_DUTY field is RO: its value indicates the current duty cycle of the FANPWM out-
put. During spin-up PWM_DUTY field is 0.
A value of 00h represents 0% duty cycle; a value of FFh represents 100% duty cycle.
