48 / 52 page ![]() REV. C –48– ADT7463 Table XXXII. Register 0x74 – Interrupt Mask Register 1 (Power-On Default <7:0> = 0x00) Bit Name R/W Description 0 2.5V Read/Write A one masks SMBALERT for out-of-limit conditions on the 2.5 V channel. 1VCCP Read/Write A one masks SMBALERT for out-of-limit conditions on the VCCP channel. 2VCC Read/Write A one masks SMBALERT for out-of-limit conditions on the VCC channel. 35V Read/Write A one masks SMBALERT for out-of-limit conditions on the 5 V channel. 4 R1T Read/Write A one masks SMBALERT for out-of-limit conditions on the Remote 1 Temperature channel. 5LT Read/Write A one masks SMBALERT for out-of-limit conditions on the Local Temperature channel. 6 R2T Read/Write A one masks SMBALERT for out-of-limit conditions on the Remote 2 Temperature channel. 7 OOL Read/Write A one masks SMBALERT for any out-of-limit condition in Status Register 2. Table XXXIII. Register 0x75 – Interrupt Mask Register 2 (Power-On Default <7:0> = 0x00) Bit Name R/W Description 0 12V/VC Read/Write A one masks SMBALERT for out-of-limit conditions on the 12 V channel. 1 OVT Read Only A one masks SMBALERT for overtemperature THERM conditions. 2 FAN1 Read/Write A one masks SMBALERT for a Fan 1 Fault. 3 FAN2 Read/Write A one masks SMBALERT for a Fan 2 Fault. 4 FAN3 Read/Write A one masks SMBALERT for a Fan 3 Fault. 5 F4P Read/Write A one masks SMBALERT for a Fan 4 Fault. If the TACH4 pin is being used as the THERM input, this bit masks SMBALERT for a THERM timer event. 6D1 Read/Write A one masks SMBALERT for a diode open or short on Remote 1 channel. 7D2 Read/Write A one masks SMBALERT for a diode open or short on Remote 2 channel. Table XXXIV. Register 0x76 – Extended Resolution Register 1 Bit Name R/W Description <1:0> 2.5V Read-Only 2.5 V LSBs. Holds the 2 LSBs of the 10-bit 2.5 V measurement. <3:2> VCCP Read-Only VCCP LSBs. Holds the 2 LSBs of the 10-bit VCCP measurement. <5:4> VCC Read-Only VCC LSBs. Holds the 2 LSBs of the 10-bit VCC measurement. <7:6> 5V Read-Only 5 V LSBs. Holds the 2 LSBs of the 10-bit 5 V measurement. If this register is read, this register and the registers holding the MSB of each reading are frozen until read. Table XXXV. Register 0x77 – Extended Resolution Register 2 Bit Name R/W Description <1:0> 12V Read-Only 12 V LSBs. Holds the 2 LSBs of the 10-bit 12 V measurement. <3:2> TDM1 Read-Only Remote 1 Temperature LSBs. Holds the 2 LSBs of the 10-bit Remote 1 Temperature measurement. <5:4> LTMP Read-Only Local Temperature LSBs. Holds the 2 LSBs of the 10-bit Local Temperature measurement. <7:6> TDM2 Read-Only Remote 2 Temperature LSBs. Holds the 2 LSBs of the 10-bit Remote 2 Temperature measurement. If this register is read, this register and the registers holding the MSB of each reading are frozen until read. Rev. 4 | Page 48 of 52 | www.onsemi.com |
