The RUNTCELLI bit indicates that TENB was detected as being deasserted before the end of
the cell transfer when operating in UTOPIA Level 3™ mode. This will result in a partial cell
transfer and an erroneous cell will be passed to the TXSDQ. Possible causes are incorrect
setting in the size of the cell expected by this interface. If WCIMODE is set to logic 1, only
over-writing with a ‘1’ clears this bit. If WCIMODE is set to logic 0, then a read of this
register automatically clears the bit.
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 erroneous and sent
on to the TXSDQ. ATM cell transmission is not affected by parity errors. If WCIMODE is
set to logic 1, only over-writing with a ‘1’ clears this bit. If WCIMODE is set to logic 0, then
a read of this register automatically clears the bit.
