RUNTCELLI
The RUNTCELLI bit indicates that TENB was detected as being deasserted before the end of
the cell transfer when operating in Utopia L3 mode. This will result in a partial cell transfer
and an erred cell will passed to the TXSDQ. Possible causes are incorrect setting in the size
of the cell expected by this interface. The RUNTCELLI bit is cleared when this register is
read.
TPARERRI
The TPARERR bit is used to indicate that a Parity Error was observed on the incoming TDAT
bus since the last time the interrupt was read. The packet will be marked erred and sent on
to the TXSDQ. ATM cell transmission is not affected by parity errors. The TPARERRI bit is
cleared when this register is read.
TDTFERRI
The TDTFERR bit is used to indicate that a Data Field mismatch was observed on the
incoming TDAT[31:24] bus compared to the ATM/packet selection for that PHY configuration
(selection done using the POS_SEL bits in the TXSDQ FIFO Indirect Configuration register).
This bit is cleared on microprocessor read.
