The data format used for allocating data in the Master is shown below. Data is
allocated as two's complements (4 bytes = 2 words).

This format is used to allocate temperature data in 1/100 Display Mode. The
data format used when allocated in the Master is shown below. The data is
given as two's complements (8 bytes = 4 words).

These flags turn ON for the one-shot time when detecting the top or valley for
the top/valley hold function.
These flags are used to time reading the values held as the top and valley val-
ues at the Master. The following data format is used when these flags are allo-
cated in the Master (2 bytes = 1 word).

+1 T_STx
Note The one-shot time can be changed. For details, refer to the one-shot time set-
tings for the top/valley hold function.
The Temperature Status Flags include allocations for the Comparator Result
Flag, the Top/Valley Detection Timing Flags, and the Off-wire Detection Flags.
These flags are used for detection and monitoring.
The data format used for each byte when these flags are allocated in the Mas-
ter is shown below (2 bytes = 1 word).

Turns ON when a valley is
detected by the valley hold
function and then turns OFF
after the one-shot time has
elapsed.
Turns ON when a top is
detected by the top hold func-
tion and then turns OFF after
the one-shot time has elapsed.
