In a multiple CPU system, the multiple CPU auto
refresh setting is any of the following:
– When a bit device is specified as a refresh
device, a number other than a multiple of 16
is specified for the refresh-starting device.
– The device specified is other than the one that
may be specified.
– The number of send points is an odd number.

– When specifying the bit device, specify 0 or a
multiple of 16 for the refresh starting device.
– Specify the device that may be specified for
the refresh device.
– Set the number of send points to an even
