Waiting for end of duplex synchronization
Beginning of duplex synchronization
Duplex status is checked (i.e., whether the Unit status is active
or standby).
Data is transferred from the active CPU Unit to the standby
CPU Unit, and verified. (Details are provided below.)
In a Duplex CPU System, synchronization processing is exe-
cuted in order to coordinate the timing of active and standby
CPU Unit operations.
