PWM DUTY CYCLE REGISTERS
Reg. 0x30 PWM1 Duty Cycle = 0xFF (100% default)
Reg. 0x31 PWM2 Duty Cycle = 0xFF (100% default)
Reg. 0x32 PWM3 Duty Cycle = 0xFF (100% default)
By reading the PWMx Current Duty Cycle Registers, you can
keep track of the current duty cycle on each PWM output, even
when the fans are running in Automatic Fan Speed Control
Mode or Acoustic Enhancement Mode.

OPERATING FROM 3.3 V STANDBY
The ADT7460 has been specifically designed to operate from a
3.3 V STBY supply. In computers that support S3 and S5
states, the core voltage of the processor will be lowered in these
states. If using the Dynamic T
MIN
Mode, lowering the core
voltage of the processor would change the CPU temperature
and change
the dynamics of the system under dynamic T
MIN
control.
Likewise, when monitoring
THERM
, the
THERM
timer
should be disabled during these states.
XOR TREE TEST MODE
The ADT7460 includes an XOR Tree Test Mode. This mode is
useful for in-circuit test equipment at board-level testing. By
applying stimulus to the pins included in the XOR Tree, it is
possible to detect opens or shorts on the system board. Figure 38
shows the signals that are exercised in the XOR Tree Test Mode.

Figure 38. XOR Tree Test
The XOR Tree Test is invoked by setting Bit 0 (XEN) of the
XOR Tree Test Enable Register (Reg. 0x6F).
