64 / 84 page RPM-Based Fan Controller with HW Thermal Shutdown Datasheet Revision 0.85 (01-29-08) 64 SMSC EMC2103 DATASHEET Bit 4 - RPM / PWM - This bit selects the data format for the LUT drive settings. ‘0’ (default) - The Look Up Table drive settings are RPM TACH count values for use by the RPM based Fan Speed Control Algorithm. The Look Up Table drive settings should be loaded highest value to lowest value (to coincide with the inversion between TACH counts and actual RPM). ‘1’ - The Look Up Table drive settings are PWM duty cycle values and are used directly. The drive settings should be loaded lowest value to highest value. Bit 2 - TEMP3_CFG - Determine the temperature channel that is used for the Temperature 3 inputs to the Look Up Table. If the External Diode 3 channel is not enabled, then the Temperature 3 inputs are not used by the Look Up Table. ‘0’ (default) - The External Diode 3 channel is used by the Fan Look Up Table (if enabled). ‘1’ - The data written into the Pushed Temperature 1 Register is used by the Fan Look Up Table. Bit 0 - TEMP4_CFG - Determine the temperature channel that is used for the Temperature 4 inputs to the Look Up Table. ‘0’ (default) - The Internal channel is used by the Fan Look Up Table. ‘1’ - The data written into the Pushed Temperature 2 Register is used by the Fan Look Up Table. 6.33 Look Up Table Registers Table 6.49 Look Up Table Registers ADDR R/W REGISTER RPM / PWM B7 B6 B5 B4B3 B2B1 B0 DEFAULT 51h R/W LUT Drive Setting 1 ‘0’ 4096 2048 1024 512 256 128 64 32 FBh ‘1’ 128 64 32 16 8 4 2 1 52h R/W LUT Ext Diode 1 Setting 1 X - 64 32 16 8 4 2 1 7Fh (127°C) 53h R/W LUT Ext Diode 2 Setting 1 X - 64 32 16 8 4 2 1 7Fh (127°C) 54h R/W LUT Temp 3 Setting 1 X - 64 32 16 8 4 2 1 7Fh (127°C) 55h R/W LUT Temp 4 Setting 1 X - 64 32 16 8 4 2 1 7Fh (127°C) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 74h R/W LUT Drive Setting 8 ‘0’ 4096 2048 1024 512 256 128 64 32 92h ‘1’ 128 64 32 16 8 4 2 1 75h R/W LUT Ext Diode 1 Setting 8 X - 64 32 16 8 4 2 1 7Fh (127°C) 76h R/W LUT Ext Diode 2 Setting 8 X - 64 32 16 8 4 2 1 7Fh (127°C) 77h R/W LUT Temp 3 Setting 8 X - 64 32 16 8 4 2 1 7Fh (127°C) |
