PRODUCTION DATA
All temperature limits are 11 bits with three LSBs always '0'. Only eight MSBs need to be set in one register for each limit.
Bit 7 (MSB) | Bit 6 | Bit 5 | Bit 4 | Bit 3 | Bit 2 | Bit 1 | Bit 0 (LSB) |
---|---|---|---|---|---|---|---|
LT-H10 (MSB) | LT-H9 | LT-H8 | LT-H7 | LT-H6 | LT-H5 | LT-H4 | LT-H3 |
These bits are the upper bounds of the local temperature.

0 | 0 | PSV8 | PSV7 | PSV6 | PSV5 | PSV4 | PSV3 |
Bits [PSV10:PSV0] are the passive cooling temperature threshold. Bits PSV10, PSV9, and [PSV2:PSV0] are always '0'. The PSV ranges from 0°C to +64°C.
In the auto fan temperature loop, the fan stops and the duty cycle is forced to 0% when the active temperature is equal to or below the PSV temperature.
