11 / 32 page  © 2006 Microchip Technology Inc. DS21935C-page 11 TCN75A 5.3 Registers The TCN75A has four registers that are user-accessi- ble. These registers are specified as the Ambient Temperature (TA) register, the Temperature Limit-set (TSET) register, the Temperature Hysteresis (THYST) register and device Configuration (CONFIG) register. The Ambient Temperature register is a read-only register and is used to access the ambient temperature data. The data from the ADC is loaded in parallel in the register. The Temperature Limit-set and Temperature Hysteresis registers are read/write registers that provide user-programmable temperature limits. If the ambient temperature drifts beyond the programmed limits, the TCN75A outputs an alert signal using the ALERT pin (refer to Section 5.3.4.3 “ALERT Output Configuration”). The device Configuration register provides access for the user to configure the TCN75A’s various features. These registers are described in further detail in the following sections. The registers are accessed by sending register pointers to the TCN75A using the serial interface. This is an 8-bit pointer. However, the two Least Significant bits (LSbs) are used as pointers and all other bits need to be cleared <0>. This device has additional registers that are reserved for test and calibration. If these registers are accessed, the device may not perform according to the specification. The pointer description is shown below. FIGURE 4-2: Register Block Diagram.
