Preliminary V2.0 Nov. 2, 1998 40 Silicon Integrated Systems Corporation
The cycle time of the pulses from the tachometer output is measured by a counter counting
up at 22.5KHz clock. The reading of counter can be derived from the following formula. At
the nominal speed, a reading of 153 is expected.
Count = 22500 * 60 / RPM * Divisor
Where:
RPM is the fan’s nominal rotations per minute
Divisor is the normalized factor programmed in the fan divisor register in order to get a
reading of 153 at nominal speed for every RPM. It should be:
8800RPM : 1
4400RPM : 2
2200RPM : 4
1100RPM : 8
If the speed of fan decreases, the reading should go up until the maximum reading of 255 is
reached. This may indicate that the fan speed is very slow or has already stopped. There is
no upper limit for the fan speed; only lower limit can be programmed. Once the lower limit is
exceeded, a SMI# or IRQ can be generated to inform the operating software to take proper
steps such as throttling CPU activities by asserting the STPCLK#.
3.5.4 THE ROUND-ROBIN SAMPLING CYCLE
Once the monitoring process is started by setting a 1 to the Start bit at Configuration register,
the Data Acquisition Module will start sampling the inputs from each sources in a round-robin
manner according to the following order:
(1) Reserved (2) VIN0 (3) VIN1 (4) VIN2 (5) VIN3 (6) DXP/VIN4 (7) FAN1 (8) FAN2
A complete round-robin cycle will be completed with the rate of approximately 8/7second,
and the switch time for the eight input sources is evenly distributed within one cycle, i.e., 1/7
second. This gives the ADC enough time to provide a stable value before switching to the
next input. The readings for each input sources will be updated approximately once every
8/7 second and can be read from these offset registers.
