Both operational modes are represented in Figure 12. Table 11, Table 12, Table 13, and Table 14 describe the

format for the THIGH and TLOW registers. The most significant byte is sent first, followed by the least significant

byte. Power-up reset values for THIGH and TLOW are:

THIGH = 80°C and TLOW = 75°C

The format of the data for THIGH and TLOW is the same as for the Temperature register.

All 12 bits for the Temperature, THIGH, and TLOW registers are used in the comparisons for the Alert function for

all converter resolutions. The three LSBs in THIGH and TLOW can affect the Alert output even if the converter is

configured for 9-bit resolution.
