ATM: Transmit UTOPIAATM Layer
Cell Available is an active high
signal from the PHY layer device to
indicate that there is sufficient room
to accept a cell.
PHY: Receive UTOPIA/Any-PHY
PHY Layer Cell Available is an
active high signal asserted by the
AAL1gator-8 to indicate it is ready to
deliver a complete cell. In Utopia
Level 2 mode, this signal is driven
only when MPHY_ADD matches
CFG_ADDR in the
UI_SRC_ADD_CFG register in the
previous cycle. A pulldown resistor
is recommended.
Any-PHY: This pin is the Receive
Packet Available (RPA) signal which
functions the same as RPHY_CLAV
except for it is activated two cycles
after a matching address instead of
one.
