45 / 56 page  REV. A ADM1027 –45– Table XII. Register 0x43 – VID Register (Power-On Default = 0x00 ) Bit Name R/W Description <4:0> VID[4:0] Read-Only The VID[4:0] inputs from the CPU to indicate the expected processor core voltage. On power-up, these bits reflect the state of the VID pins, even if monitoring is not enabled. <7:5> Reserved Read-Only Reserved for future use. Table XIII. Voltage Limit Registers Register Address R/W Description Power-On Default 0x44 Read/Write 2.5 V Low Limit 0x00 0x45 Read/Write 2.5 V High Limit 0xFF 0x46 Read/Write VCCP Low Limit 0x00 0x47 Read/Write VCCP High Limit 0xFF 0x48 Read/Write VCC Low Limit 0x00 0x49 Read/Write VCC High Limit 0xFF 0x4A Read/Write 5 V Low Limit 0x00 0x4B Read/Write 5 V High Limit 0xFF 0x4C Read/Write 12 V Low Limit 0x00 0x4D Read/Write 12 V High Limit 0xFF Setting the Configuration Register 1 lock bit has no effect on these registers. High Limits: An interrupt is generated when a value exceeds its high limit ( > comparison). Low Limits: An interrupt is generated when a value is equal to or below its low limit ( £ comparison). Table XIV. Temperature Limit Registers Register Address R/W Description Power-On Default 0x4E Read/Write Remote 1 Temperature Low Limit 0x81 0x4F Read/Write Remote 1 Temperature High Limit 0x7F 0x50 Read/Write Local Temperature Low Limit 0x81 0x51 Read/Write Local Temperature High Limit 0x7F 0x52 Read/Write Remote 2 Temperature Low Limit 0x81 0x53 Read/Write Remote 2 Temperature High Limit 0x7F Exceeding any of these temperature limits by 1 oC will cause the appropriate status bit to be set in the interrupt status register. Setting the Configuration Register 1 lock bit has no effect on these registers. High Limits: An interrupt is generated when a value exceeds its high limit ( > comparison). Low Limits: An interrupt is generated when a value is equal to or below its low limit ( £ comparison). |
