Input
Input
PHY: Receive UTOPIA PHY Layer
Address (Bits 4 to 0) which selects
the UTOPIA receiver. These inputs
are used as an output enable for
RPHY_CLAV and to validate the
activation of RPHY_ENB. There are
internal pull-up resistors. These pins
are compared with CFG_ADDR[5:0]
in the UI_SRC_CFG_ADDR
register.
ANY-PHY: Receive Start
Transfer(RSX) is an active high
output which indicates the start of
an Any-PHY packet which identifies
the location of the prepended
address. ANY-PHY_EN in
UI_SRC_CFG register needs to be
set for this function.
Receive Chip Select Bar (RCSB) is
an active low input which is used to
select the AAL1gator-8 when polling
in Any-PHY mode. This input is
used to decode any Any-PHY
address bits greater than
RPHY_ADD[2]. This input goes low
one cycle after Any-PHY address is
valid.
ANY-PHY_EN and CS_MODE_EN
in UI_SRC_CFG register needs to
be set for this function. Otherwise
this bit functions as RPHY_ADD[3].
RPHY_ADD[2:0] is the bottom three
bits of the Any-PHY address and is
used to select the device when
polling. These pins are compared
with CFG_ADDR[2:0] in the
UI_SRC_CFG_ADDR register.
Note these pins must be tied to
ground when not used.
