Description
PWM1 Current Duty Cycle (0% to 100% duty cycle = 0x00 to 0xFF)
PWM2 Current Duty Cycle (0% to 100% duty cycle = 0x00 to 0xFF)
PWM3 Current Duty Cycle (0% to 100% duty cycle = 0x00 to 0xFF)
These registers reflect the PWM duty cycle driving each fan at any given time. When in Automatic Fan Speed Control Mode, the ADT7460 reports the PWM duty
cycles back through these registers. The PWM duty cycle values will vary according to temperature in Automatic Fan Speed Control Mode. During fan startup, these
registers report back 0x00. In Software Mode, the PWM duty cycle outputs can be set to any duty cycle value by writing to these registers.

Description
Remote 1 Operating Point Register (default = 100 C)
Local Temp Operating Point Register (default = 100 C)
Remote 2 Operating Point Register (default = 100 C)
These registers set the target Operating Point for each temperature channel when the Dynamic T
MIN
Control feature is enabled.
The fans being controlled will be adjusted to maintain temperature about an Operating Point.
*
These registers become read-only when the Configuration Register 1 Lock bit is set to 1. Any subsequent attempts to write to these registers will fail.
