X This memory space contains 256 active-high
enable bits. Each bit represents a multicast net
number from 0 through 255. If a bit is set, the cor-
responding multicast addressed data cell is sent to
the queue group for PHY port 0, or the corre-
sponding multicast control cell is sent to the control
cell receive direct and extended memory. The
least significant bit is multicast net number 0. This
memory space in direct memory is a shadow of the
PHY port 0 and control cells multicast extended
memory space.
