Function
ATM Transmit Buffer Threshold
Crossing
Indicates if the difference between the write
and read pointer of the mapping buffer
became smaller than a SW selectable
threshold
Uncorrectable HEC Error
Indicates if a cell has been discarded due to
an uncorrectable HEC error
Port Number
Indicates the port number where the cell
causing ATBT or UNCHEC being asserted
came from
Function
UTOPIA Transmit Enable
Slave:
ATM layer during cycles when
TXDAT[0:7]
Master:
the PHY layer during cycles when
TXDAT[0:7]
UTOPIA Transmit Address Bus
Five bit wide true data driven from the ATM
to MPHY layer to poll and select the
appropriate MPHY device. TXADR4 is the
MSB.
