ATM: Receive UTOPIAATM Layer
Cell Available is an active high
signal asserted by the PHY layer to
indicate that there is a cell available
to send.
PHY: Receive UTOPIA/Any-PHY
PHY Layer Cell Available is an
active high signal asserted by the
AAL1gator-8 to indicate there is a
cell-space available. The
AAL1gator-8 drives this signal only
when TPHY_ADD matches
CFG_ADDR in the UI_SNK_CFG
register in the previous cycle. A
pulldown resistor is recommended.
Any-PHY: This pin is the Transmit
Packet Available (TPA) signal which
functions the same as TPHY_CLAV
except for it is activated two cycles
after a matching address instead of
one.
