c) TCRIT3 Mask Register, Status Register 1 and 4, and TCRIT3 output logic diagram.
If enabled, local temperature is compared to the user programmable 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 13).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 14). The comparison result can also
be read back from the Status Register 2, Status Register 3 and Status Register 4.
