Table III. ADM1028 Registers
Register Name
Address A7–A0 in Hex
Comments
Value Registers
0x14–0x38
See Table IV
Company ID
0x3E
This location will contain the company identification number. This
register is read only.
Revision
0x3F
This location will contain the revision number of the part in the
lower four bits of the register [3:0]. The upper four bits reflect the
ADM1028 Version Number [7:4]. The first version is 1101. The
next version of ADM1028 would be 1110, etc. For instance, if the
stepping were A0 and this part is an ADM1028, this register would
read 1101 0000. This register is read only.
Configuration Register
0x40
See Table V. Power-on value = 0010 0001.
Interrupt Status Register
0x41
See Table VI. Power-on value = 0000 0000.
Interrupt Mask Register
0x43
See Table VII. Power-on value = 0000 0000.
Manufacturer Test
0x44–0x4A
Test Registers for manufacturer’s use only. Do not write to these
registers.
Remote Function
0x4B
See Table VIII. Power-on value = 0000 0000.
Alert Status
0x4C
See Table IX. Power-on value = 0000 0000.
Fan Speed Ramp Register
0xCO
See Table X. Power-on value = 0000 0000.
