The Hold Flags are used with the peak/bottom hold and top/valley hold func-
tions. They are used to control the hold execution timing from the Master Unit.
They are allocated in the Master Unit using the following data format (1 word
(2 bytes)).
Note A transmission delay may occur between when the Master Unit's power is
turned ON and the status of the Hold Flag is transferred to the Temperature
Input Unit.
