43 / 88 page  RPM-Based Fan Controller with Multiple Temperature Zones & Hardware Thermal Shutdown Datasheet 2013 Microchip Technology Inc. DS20005251A-page 43 During Power-On-Reset (POR), the default values are stored in the registers. A POR is initiated when power is first applied to the part and the voltage on the VDD supply surpasses the POR level as specified in the electrical characteristics. Any reads to undefined registers will return 00h. Writes to undefined registers will not have an effect. 7.1.1 Lock Entries The Lock Column describes the locking mechanism, if any, used for individual registers. All SWL registers are Software Locked and therefore made read-only when the LOCK bit is set. 76h R/W LUT Temp 2 Setting 8 Stores the threshold level for the External Diode 2 channel that is associated with the Drive 8 value 7Fh (127°C) LUT Lock Page 68 77h R/W LUT Temp 3 Setting 8 Stores the threshold level for the External Diode 3 channel (or Pushed Temp 1 temp) that is associated with the Drive 8 value 7Fh (127°C) LUT Lock Page 68 78h R/W LUT Temp 4 Setting 8 Stores the threshold level for the Internal Diode channel (or Pushed Temp 2 temp) that is associated with the Drive 8 value 7Fh (127°C) LUT Lock Page 68 79h R/W LUT Temp 1 Hysteresis Stores the hysteresis that is used in the LUT for the Temp 1 Settings 0Ah (10°C) LUT Lock Page 68 7Ah R/W LUT Temp 2 Hysteresis Stores the hysteresis that is used in the LUT for the Temp 2 Settings 0Ah (10°C) LUT Lock Page 68 7Bh R/W LUT Temp 3 Hysteresis Stores the hysteresis that is used in the LUT for the Temp 3 Settings 0Ah (10°C) LUT Lock Page 68 7Ch R/W LUT Temp 4 Hysteresis Stores the hysteresis that is used in the LUT for the Temp 4 Settings 0Ah (10°C) LUT Lock Page 68 7Dh R/W LUT Configuration Stores and controls the configuration for the LUT 00h No Page 67 Lock Register EFh R/W Software Lock Locks all SWL registers 00h SWL Page 70 Revision Registers FCh R Product Features Indicates which pin selected options are enabled 00h No Page 70 FDh R Product ID Stores the unique Product ID 2Eh No Page 71 FEh R Manufacturer ID Manufacturer ID 5Dh No Page 72 FFh R Revision Revision 81h No Page 72 Table 7.1 EMC2113 Register Set (continued) ADDR R/W REGISTER NAME FUNCTION DEFAULT VALUE LOCK PAGE |
