20 / 86 page  Fan Control Device with Hardware Monitoring and Acoustic Noise Reduction Features Datasheet Revision 0.4 (06-15-06) 20 SMSC EMC6D102 DATASHEET The continuous monitoring function is started by doing a write to the Ready/Lock/Start Register, setting the Start bit (Bit 0) high. The part then performs a “round robin” sampling of the inputs, in the order shown below (see Table 5.3). Sampling of all values occurs in a nominal 223 ms (default - see Table 5.2, “Conversion Cycle Timing,” on page 19). When the continuous monitoring function is started, it cycles through each measurement in sequence, and it continuously loops through the sequence approximately once every 223 ms (default - see Table 5.2, “Conversion Cycle Timing,” on page 19). Each measured value is compared to values stored in the Limit registers. When the measured value violates the programmed limit the Hardware Monitor Block will set a corresponding status bit in the Interrupt Status Registers. If auto fan option is selected, the hardware will adjust the operation of the fans accordingly. See Auto Fan Control Operating Mode on page 30. The results of the sampling and conversions can be found in the Reading Registers and are available at any time. 5.3.2 Cycle Monitoring Mode In cycle monitoring mode, the part completes all sampling and conversions, then waits approximately one second to repeat the process. It repeats the sampling and conversion process typically every 1.2 seconds (1.4 sec max - default averaging enabled). The sampling and conversion of each voltage and temperature reading is performed once every monitoring cycle. This is a power saving mode. The cycle monitoring function is started by doing a write to the Ready/Lock/Start Register, setting the Start bit (Bit 0) high. The part then performs a “round robin” sampling of the inputs, in the order shown above. When the cycle monitoring function is started, it cycles through each measurement in sequence, and it produces a converted voltage and temperature reading for each input. The state machine waits approximately one second before repeating this process. Each measured value is compared to values stored in the Limit registers. When the measured value violates (or is equal to) the programmed limit the Hardware Monitor Block will set a corresponding status bit in the Interrupt Status Registers. If auto fan option is selected, the hardware will adjust the operation of the fans accordingly. See the section titled Auto Fan Control Operating Mode on page 30. The results of each sampling and conversion can be found in the Reading Registers and are available at any time, however, they are only updated once per conversion cycle.
