9 / 15 page PRODUCT SPECIFICATION FM75 REV. 1.0.5 10/2/03 9 Over-Limit-Signal Temperature Register (TOS) The TOS Register is a two-byte (16-bit) read/write register that stores the user-programmable upper trip-point temperature for the thermal alarm in two’s-complement format. At power-up this register defaults to 80°C (i.e., 0101 0000 0000 0000). The format of the TOS register is identical to that of the Temperature Register (see Figure 6). The 4 LSBs of the TOS Register are hardwired to zero, so data written to these register bits will be ignored. The MSB position of the TOS Register contains the sign bit for the digital temperature and bit 14 contains the temperature MSB. The resolution setting for the T-to-D conversion determines how many bits of the TOS Register are used by the thermal alarm. For example, for 9-bit conversions the trip-point temperature is defined by the 9 MSBs of the TOS register, and all remaining bits are “don’t cares.” Hysteresis Temperature Register (THYST) The THYST Register is a two-byte (16-bit) read/write register that stores the user programmable lower trip-point temperature for the thermal alarm in two’s-complement format. At power-up this register defaults to 75°C (i.e., 0100 1011 0000 0000). The THYST register is illustrated in Figure 6. The format of this register is the same as that of the Temperature Register. The 4 LSBs of the THYST register are hardwired to zero, so data written to these bits is ignored. The resolution setting for the T-to-D conversion determines how many bits of the THYST Register are used by the thermal alarm. For example, for 9-bit conversions the hysteresis temperature is defined by the 9 MSBs of the THYST Register, and all remaining bits are “don’t cares.” .
