REGISTER DESCRIPTION
In this section, all interrupts are the interrupt signal through the SMBALERT pin, unless otherwise noted.
DEVICE CONFIGURATION REGISTERS
AMC6821
SBAS386A–MAY 2006–REVISED MAY 2006
Configuration Register 1 (Address 0x00, Value After Power-On Reset = 0xD4)
BIT
NAME
R/W
DEFAULT
DESCRIPTION
THERM interrupt enable. When this bit is set, the THERM interrupt is enabled.
L-THERM = 1 or R-THERM = 1 causes an interrupt. When this bit is cleared ('0'), the
THERM interrupt is disabled. When disabled, L-THERM = 1 or R-THERM = 1 does not
assert the SMBALERT pin, but forces the THERM pin low. Power-on default = 1.
Fan driver control bit 1. Power-on default = 1. Refer to
Table 8
.
Fan driver control bit 0. Power-on default = 0. Refer to
Table 8
.
Setting this pin to '1' enables the FAN-FAULT pin. Clearing this pin ('0') disables the
FAN-FAULT pin (always in Hi-Z). Power-on default = 1.
PWM invert bit. When PWMINV = 0 (default), the PWM-Out pin goes low for 100% duty
cycle (suitable for driving the fan using a PMOS device). Setting PWMINV to '1' makes
the PWM-Out pin go high (with an external pull-up resistor) for 100% duty cycle
(suitable for driving the fan using a NMOS device). Power-on default = 0.
Fan RPM interrupt enable bit. Power-on default = 1. When FANIE = 1, the FAN-RPM
interrupt is enabled. FANS = 1 or RPM-ALARM = 1 generates a FANORN interrupt,
making the SMBALERT pin go low. When FANIE = 0, a FAN-RPM interrupt is disabled.
FANORN = 1 does not generate an interrupt.
Setting this bit to '1' enables the interrupt from the SMBALERT pin. Clearing this bit ('0')
disables the interrupt. Power-on default = 0.
'1' enables monitoring (temperatures and RPM) and PWM outputs. '0' disables
monitoring and PWM output. All registers should be programmed by BIOS before setting
this bit to 1. Power-on default = 0.

FUNCTION
Maximum fast speed calculated by the local temperature-fan control and the remote
temperature-fan control.
Auto remote-temperature-fan control. The PWM duty cycle is controlled by the remote
temperature. Power-on default mode.
Software DCY control. Host writes DCY register to set the PWM duty cycle.
Software RPM control. Host writes the TACH setting register with the value corresponding
to the desired RPM. The device measures the actual RPM and adjusts the PWM duty cycle
to maintain the fan speed to the desired value.
