Description
Programmable Local Temp Sensor Automatic Trip Point - default 70 degrees C.
This register can only be written to if the write once bit in the configuration register
(0x40, bit 3) has not been set.
Programmable Remote Thermal Diode Automatic Trip Point - default 100 degrees C.
This register can only be written to if the write once bit in the configuration register
(0x40, bit 3) has not been set.
Test register for manufacturer’s use only. Do not write to this register
Default Local Temp Sensor Automatic Trip Point - default 70 degrees C
Cannot be changed. Disabled when bit 3 of Config. register is set

Comments
See Table 8
This location will contain the company identification
number. This register is read only.
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 ADM1022 Version Number
[7:4]. The first version is 1100. The next version of
ADM1022 would be 1101, etc. For instance, if the
stepping were A0 and this part is a ADM1022, then
this register would read 1100 0000. This register is
read only.
Power on value = 0010 0101
Power on value = 0000 0000
Power on value = 0000 0000
Power on value = 0000 0000
