The temperature reading is in 癈 using a 16-bit sign-
extended twos complement format. Table 1 shows
examples of temperature and the corresponding data
for 12-bit resolution. With twos complement, the sign
bit(s) is set if the value is negative. If the device is con-
figured for 12-bit resolution, all bits in the LS byte are
valid; for a reduced resolution, bit 0 (11-bit mode), bits
0 to 1 (10-bit mode), and bits 0 to 2 (9-bit mode) are
undefined.
The result of a temperature conversion is automatically
compared to the values in the alarm registers to deter-
mine whether an alarm condition exists. Alarm thresh-
olds are represented as twos complement number.
With 8 bits available for sign and value, alarm thresh-
olds can be set in increments of 1癈. An alarm condi-
tion exists if a temperature conversion results in a value
that is either higher than or equal to the value stored
in the TH register or lower than or equal to the value
stored in the TL register. If a temperature alarm condi-
tion exists, the device responds to the Conditional
Search ROM command. The alarm condition is cleared
if a subsequent temperature conversion results in a
temperature reading within the boundaries defined by
the data in the TH and TL registers.
