Configuration register 1:
Bits [7:5]: Setting the fan-speed control mode:
Bit 7 = 1: Enables automatic fan-speed control mode.
Bits [6:5] = 00: Remote temperature controls the fan speed.
Bits [6:5] =11: Both remote and local temperature control the fan speed.
Bit 7 = 0, Enables PWM control mode or RPM control mode.
Bits [6:5] = X0: PWM duty cycle control mode.
Bits [6:5] = X1: RPM control mode.
Bit 4: FAN_FAULT output enable:
  1: FAN_FAULT output enabled; 0: (default) FAN_FAULT output disabled.
Bit 3: Invert the PWM output:
  0: (default) PWM active low; 1: (inverted) PWM active high.
Bit 2: TACHOMETER digital/analog input selection:
  0: (default) TACHOMETER is a logic input; 1: TACHOMETER is an analog input.
Bit 1: INT output enable:
  0: INT output disabled; 1: INT output enabled.
Bit 0: Monitoring:
  0: sleep mode; 1: (default) active temperature monitoring and fan-speed control.
  (Keep this bit set to 1 for MAX6663.) Although the default value of this bit is 1, fan
  speed control for the MAX6653 and MAX6664 is inactive until a 1 is written
  to this bit.

Configuration register 2:
Bit 7: Reset:
Setting this bit to 1 restores all registers to POR default states; self-clears to zero
  after reset.
Bit 6: Unused.
Bit 5: Remote temperature enable:
0: interrupts disabled for remote channel; 1: interrupts enabled for remote
  channel; defaults to 1 unless a diode fault is detected on power-up.
Bit 4: Local temperature enable:
  0: interrupts disabled for local channel; 1: (default) interrupts enabled for local
  channel.
Bit 3: INT input function mask:
  0: enable INT input function; 1: (default) disable INT input function.
Bit 2: TACHOMETER input enable:
  0: disable TACHOMETER input; 1: (default) enable the TACHOMETER input.
  (Keep this bit set to 1 for MAX6663.)
Bit 1: SMBus timeout enable:
  0: SMBus timeout disabled; 1: (default) SMBus timeout enabled.
Bit 0: PWM out enable:
  0: PWM output disabled; 1: (default) PWM output enabled.
