ATM: Receive UTOPIAATM Layer
Enable is an active low signal
asserted by the AAL1gator-8 to
indicate RATM_D and RATM_SOC
will be sampled at the end of the
next cycle. It will not be asserted
until the AAL1gator-8 is ready to
receive a full cell.
PHY: Transmit UTOPIA/Any-PHY
PHY Layer Enable is an active low
signal asserted by the ATM layer
device during cycles when
TPHY_D[15:0] contain valid data.
The AAL1gator-8 will accept data
only if TPHY_ADD matches
CFG_ADDR in the UI_SNK_CFG
register the cycle before TPHY_ENB
goes low
Any-PHY: This pin is the TENB
input signal, which functions the
same as TPHY_ENB.
