8.5.1.5 Temperature Limit Registers

All temperature limits are 11 bits with three LSBs always '0'. Only eight MSBs need to be set in one register for each limit.

Table 8-30 Local-High-Temp-Limit Register (Address 0x14, Value After Power-On or Reset = 0x3C, +60°C)

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.

Table 8-31 Local-Low-Temp-Limit Register (Address 0x15, Value After Power-On or Reset = 0x00, 0°C)

Bit 7 (MSB)	Bit 6	Bit 5	Bit 4	Bit 3	Bit 2	Bit 1	Bit 0 (LSB)
LT-L10 (MSB)	LT-L9	LT-L8	LT-L7	LT-L6	LT-L5	LT-L4	LT-L3

These bits are the lower bounds of the local temperature.

Table 8-32 Local-Therm-Limit Register (Address 0x16, Value After Power-On or Reset = 0x46, +70°C)

Bit 7 (MSB)	Bit 6	Bit 5	Bit 4	Bit 3	Bit 2	Bit 1	Bit 0 (LSB)
LT-T10 (MSB)	LT-T9	LT-T8	LT-T7	LT-T6	LT-T5	LT-T4	LT-T3

These bits are the thermal threshold of the local temperature.

Table 8-33 Remote-High-Temp-Limit Register (Address 0x18, Value After Power-On or Reset = 0x50, +80°C)

Bit 7 (MSB)	Bit 6	Bit 5	Bit 4	Bit 3	Bit 2	Bit 1	Bit 0 (LSB)
RT-H10 (MSB)	RT-H9	RT-H8	RT-H7	RT-H6	RT-H5	RT-H4	RT-H3

These bits are the upper bounds of the remote temperature.

Table 8-34 Remote-Low-Temp-Limit Register (Address 0x19, Value After Power-On or Reset = 0x00, 0°C)

Bit 7 (MSB)	Bit 6	Bit 5	Bit 4	Bit 3	Bit 2	Bit 1	Bit 0 (LSB)
RT-L10 (MSB)	RT-L9	RT-L8	RT-L7	RT-L6	RT-L5	RT-L4	RT-L3

These bits are the lower bounds of the remote temperature.

Table 8-35 Remote-Therm-Limit Register (Address 0x1A, Value After Power-On or Reset = 0x64, +100°C)

Bit 7 (MSB)	Bit 6	Bit 5	Bit 4	Bit 3	Bit 2	Bit 1	Bit 0 (LSB)
RT-T10 (MSB)	RT-T9	RT-T8	RT-T7	RT-T6	RT-T5	RT-T4	RT-T3

These bits are the thermal threshold of the remote temperature.

Table 8-36 Local-Critical-Temp Register (Address 0x1B, Value After Power-On or Reset = 0x50, +80°C)

Bit 7 (MSB)	Bit 6	Bit 5	Bit 4	Bit 3	Bit 2	Bit 1	Bit 0 (LSB)
LT-C10	LT-C9	LT-C8	LT-C7	LT-C6	LT-C5	LT-C4	LT-C3

These bits are the critical threshold of the local temperature.

Table 8-37 PSV-Temp Register (Address 0x1C, Value After Power-On or Reset = 0x00, 0°C)

Bit 7 (MSB)	Bit 6	Bit 5	Bit 4	Bit 3	Bit 2	Bit 1	Bit 0 (LSB)
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.

Table 8-38 Remote-Critical-Temp Register (Address 0x1D, Value After Power-On or Reset = 0x69, +105°C)

Bit 7 (MSB)	Bit 6	Bit 5	Bit 4	Bit 3	Bit 2	Bit 1	Bit 0 (LSB)
RT-C10	RT-C9	RT-C8	RT-C7	RT-C6	RT-C5	RT-C4	RT-C3

Bits [RT-C10:RT-C0] are the critical threshold of the remote temperature.
