54 / 99 page  Dual RPM-Based PWM Fan Controller with Hardware Thermal Shutdown Datasheet Revision 1.78 (02-28-11) 54 SMSC EMC2104 DATASHEET 6.7 REC Configuration Register The REC Configuration Register determines whether Resistance Error Correction is used for each external diode channel. The REC Configuration Register is software locked. Bit 2 - REC3 - Controls the Resistive Error Correction functionality of External Diode 3 and External Diode 4 (if APD is enabled, see Section 6.9) ‘0’ - the REC functionality for External Diode 3 is disabled ‘1’ (default) - the REC functionality for External Diode 3 is enabled. Bit 1 - REC2 - Controls the Resistive Error Correction functionality of External Diode 2. ‘0’ - the REC functionality for External Diode 2 is disabled ‘1’ (default) - the REC functionality for External Diode 2 is enabled. Bit 0 - REC1 - Controls the Resistive Error Correction functionality of External Diode 1. This bit is locked if the SHDN_SEL pin is not pulled to VDD (see Table 6.1). ‘0’ - the REC functionality for External Diode 1 is disabled ‘1’ (default) - the REC functionality for External Diode 1 is enabled. 0 0101 0.197 0 0110 0.260 0 0111 0.342 0 1000 0.449 0 1001 0.591 0 1010 0.778 0 1011 1.024 0 1100 1.348 0 1101 1.773 0 1110 2.333 0 1111 Disabled 1 X X X X Automatically detected Table 6.10 REC Configuration Register ADDR R/W REGISTER B7B6 B5B4 B3B2 B1B0 DEFAULT 17h R/W REC Configuration - - - - - REC3 REC2 REC1 07h Table 6.9 Beta Compensation Look Up Table (continued) AUTO BETAX[3:0] MINIMUM BETA 3210 |
