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 corre-
sponding multicast net number data cell is sent to
the queue group for PHY port 0, or the correspond-
ing multicast control cell is sent to the control cell
receive direct and extended memory. The least sig-
nificant bit is multicast net number 0.
