Section 7-2
The following tables show the data format used for allocating data in the Mas-
ter Unit.
Data is allocated as two's complements.

Top/Valley Detection
Timing Flags
These flags turn ON for the one-shot time when a top or valley is detected for
the top/valley hold function. These flags are allocated when detecting the time
to read the values held as the top or valley values at the Master Unit. The fol-
lowing data format is used when these flags are allocated in the Master Unit
(1 word (2 bytes)).
Each bit is described in the following table.
Note
The one-shot time can be changed. For details, refer to
11-5 Temperature
Input Unit Functions
.
Temperature Status Flags
The Temperature Status Flags include the Comparator Result Flag, the Top/
Valley Detection Timing Flags, and the Disconnected Line Detection Flags.
These flags are allocated for detection and monitoring. The data format used
for each byte when these flags are allocated in the Master Unit is shown
below (2 words (4 bytes)).

Valley Detection
Timing Flag
Turns ON when a valley is
detected by the top/valley hold
function and then turns OFF after
the one-shot time has elapsed.

T_STx
Top Detection
Timing Flag
Turns ON when a top is detected
by the top/valley hold function and
then turns OFF after the one-shot
time has elapsed.
