Critical/Thermal Shutdown Temperature Register
The Critical/Thermal Shutdown Temperature Register is a read-only register that stores the Voltage
Programmable Threshold temperature used in the Thermal / Critical Shutdown circuitry. The contents
of the register reflect the calculated temperature determined by the voltage on the TRIP_SET pin (see
The data format is shown in Table 6.5.
