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

Notes:
• In Any-PHY mode, if CS_MODE_EN=’1’ then CFG_ADDR[4:3] = “00”.else if
CS_MODE_EN=’0’ then CFG_ADDR[4]=”0”.
• In Any-PHY mode the upper 14 bits of the prepended address are compared
with CFG_ADDR[15:2]. The bottom two bits are not compared with this field
and are just used to select the target A1SP. If in 8-bit mode CFG_ADDR[7:2]
is used instead. In either case PHY_ADDR should be set to “00” when
polling.
