If enabled, local temperature is compared to the user pro-
grammable Local Tcrit Limit Register (Default Value = 85°C).
The result of this comparison is stored in Status Register 2,
Status Register 3 and Status Register 4 (see Figure 4).The
comparison result can trigger TCRIT1 pin, TCRIT2 pin or
TCRIT3 pin depending on the settings in the TCRIT1 Mask,
TCRIT2 Mask and TCRIT3 Mask Registers (see Figure 5).
The comparison result can also be read back from the Status
Register 2, Status Register 3 and Status Register 4.
If enabled, remote temperature 1 is compared to the user
programmable Remote 1 Tcrit-1 Limit Register (Default Value
110°C) and Remote 1 Tcrit-2 Limit Register (Default Value =
85°C). The result of this comparison is stored in Status Reg-
ister 2, Status Register 3 and Status Register 4 (see Figure
4). The comparison result can trigger TCRIT1 pin, TCRIT2 pin
or TCRIT3 pin depending on the settings in the TCRIT1 Mask,
TCRIT2 Mask and TRCIT3 Mask Registers (see Figure 5).
The comparison result can also be read back from the Status
Register 2, Status Register 3 and Status Register 4. The re-
mote temperature 2 operates in a similar manner to remote
temperature 1 using its associated user programmable limit
registers: Remote 2 Tcrit-1 Limit Register (Default Value 110°
C) and Remote 2 Tcrit-2 Limit Register (Default Value = 85°
C).
