Bit
Name
R/W1
Description
[6]
Local
THERM
R/W
Local THERM = 1, THERM temperature limit functionality enabled for the local temperature channel;
that is, THERM is bidirectional. Local THERM = 0, THERM is a timer input only.
THERM can also be disabled on any channel by
Writing 64C to the appropriate THERM temperature limit in Offset 64 mode.
Writing 128C to the appropriate THERM temperature limit in twos complement mode.
[7]
R2 THERM
R/W
R2 THERM = 1, THERM temperature limit functionality enabled for Remote 2 temperature channel;
that is, THERM is bidirectional. R2 THERM = 0, THERM is a timer input only.
THERM can also be disabled on any channel by
Writing 64°C to the appropriate THERM temperature limit in Offset 64 mode.
Writing 128°C to the appropriate THERM temperature limit in twos complement mode.
1 This register becomes read-only when the Configuration Register 1 lock bit is set to 1. Any further attempts to write to this register have no effect.

Pin9FUNC
Read/write
These bits set the functionality of Pin 9:
00 = TACH4 (default)
01 = THERM
10 = SMBALERT
11 = GPIO
[2]
THERM Disable
Read/write
THERM Disable = 1, disables THERM over temperature feature.
[3]
Max/Full on
THERM
Read/write
Max/Full on THERM = 0; when THERM temperature limit is exceeded, fans go to full speed.
Max/Full on THERM = 1; when THERM temperature limit is exceeded, fans go to maximum
programmed fan speed.
Max/Full on THERM = 1; when THERM limit is exceeded, fans go to maximum speed as defined in
Register 0x38, Register 0x39, Register 0x3A.

RES
THERM_LATCH
Configuration
Unused on ADT7473
On the ADT7473-1:
0 = Remote Channel 2 (default)
1 = Remote Channel 1 and Remote Channel 2
[5]
BpAttVCCP
Read/write
Bypass VCCP attenuator. When set, the measurement scale for this channel changes from 0 V (0x00)
to 2.2965 V (0xFF).

RES
Unused.
[7]
RES
Unused.
1 This register becomes read-only when the Configuration Register 1 lock bit is set to 1. Any further attempts to write to this register have no effect.
