ATM: These signals are not used in
ATM mode.
PHY: Transmit UTOPIA PHY Layer
Address (Bits 4 to 0) which selects
the UTOPIA transmitter. These
inputs are used as an output enable
for TPHY_CLAV and to validate the
activation of TPHY_ENB. There are
internal pull-up resistors. These
pins are compared with
CFG_ADDR[5:0] in the
UI_SNK_CFG_ADDR register.
ANY-PHY: Transmit Start
Transfer(TSX) is an active high input
which indicates the start of an Any-
PHY packet which identifies the
location of the prepended address.
ANY-PHY_EN in UI_SNK_CFG
register needs to be set for this
function.
Transmit Chip Select Bar (TCSB) 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
TPHY_ADD[2]. This input goes low
one cycle after Any-PHY address is
valid.
ANY-PHY_EN and CS_MODE_EN
in UI_SNK_CFG register needs to
be set for this function. Otherwise
this bit functions as TPHY_ADD[3].
TPHY_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_SNK_CFG_ADDR register.
Note these pins must be tied to
ground when not used.
