These bits contain the configured slave address used for Utopia-2 and Any-
PHY operation in the source direction. Depending on the mode of the
UTOPIA/Any-PHY interface different bits of this field are used. See Table 21
for details. In the source direction the AAL1gator is always one address.

Notes:
• In Any-PHY mode, in the SRC direction the AAL1gator will prepend the cell
with CFG_ADDR[15:0]. In 8-bit mode the cell will be prepended with
CFG_ADDR[7:0]
• In Any-PHY mode, if CS_MODE_EN=’1’ then CFG_ADDR[4:3] = “00”.
• In Any-PHY mode, if CS_MODE_EN=’0’ then CFG_ADDR[4]=”0”.
