An AnACPU can communicate with a remote module
by using the "address
on the PC CPU side".
Each control
I/O
signal to and from the
A64RDC corresponds to a device
number set by the send/received-data storage device set
by the automatic
refresh.
Thus, an AnACPU can control an A64RDC.
The A2A(SI)/A3A
CPU User's Manual (Control Functions) gives setting
