Description
2sC = 1 sets the temperature range to the twos complement temperature range.
2sC = 0 changes the temperature range to the Offset 64 temperature range. When this bit is
changed, the ADT7476 interprets all relevant temperature register values as defined by this bit.
TempOffset = 0 sets offset range to ? 63 ° C to +64 ° C with 0.5 ° C resolution.
TempOffset = 1 sets offset range to ? 63 ° C to +127 ° C with 1 ° C resolution. These settings
apply to Remote 1, Local, and Remote2 temperature offset registers (0x70, 0x71, and 0x72).
GPIO6 direction. When GPIO6 function is enabled, this determines whether GPIO6 is an
input (0) or an output (1).
GPIO6 polarity. When the GPIO6 function is enabled and is programmed as an output, this
bit determines whether the GPIO6 is active low (0) or high (1).
VID/GPIO = 0 enables VID functionality on Pin 5, Pin 6, Pin 7, Pin 8, and Pin 19.
VID/GPIO = 1 enables GPIO functionality on Pin 5, Pin 6, Pin 7, Pin 8, and Pin 19.
R1 THERM = 1 enables THERM temperature limit functionality for Remote 1 temperature
channel; that is, THERM is bidirectional.
R1 THERM = 0 indicates 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.
Local THERM = 1 enables THERM temperature limit functionality for local temperature
channel; that is, THERM is bidirectional.
Local THERM = 0 indicates 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.
R2 THERM = 1 enables THERM temperature limit functionality for Remote 2 temperature
channel; that is, THERM is bidirectional.
R2 THERM = 0 indicates 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.
