When you combine the PCU with a CJ2 CPU (unit version 1.1 or later), the PCU makes it
possible to use the synchronous unit operation function that synchronizes the CPU with the I/O
processes of the PCU at specified intervals.
This section explains an outline of the synchronous unit operation function and procedure to
use this function.
This function synchronizes the start timing of the internal processes and data exchange
between the CPU Unit and multiple Special I/O Units via synchronization signals which the
CPU Unit sends at specified intervals.
The CPU Unit can execute interrupt tasks in synchronization with data exchange with the Special
I/O Unit.
Multiple Special I/O Units synchronize the start timing of their internal processes according to
the synchronization signals from the CPU Unit.
Between the CPU Unit and multiple Special I/O Units, or among the Special I/O Units, data is
exchanged according to the timing of the synchronization signal.
To use the synchronous unit operation function, you must combine these units.
To use the synchronous unit operation function, the internal control cycle of the PCU
synchronizes with the synchronous operation cycle of the CPU Unit. Accordingly, the
responsiveness of the PCU varies depending on the synchronous operation cycle.
