Name
This bit is set if the MERROR bit in the PCI configuration
register is set. The MERROR bit is reset by either writing a
logic 1 to the MERROR bit in the PCI configuration register,
or setting the CONFIG0(PCI_ERR_RESET) bit to a logic
high.
Whenever any bit in AALx_STAT is a logic 1, AALx_STAT is
a logic 1.
When any bit in TX_STATUS is a logic 1, TX_DISCARD is
reset to 0 after the host reads the TX_STATUS register.
Read as 0.
Set when the incoming DMA burst FIFO buffer becomes
almost full.
Set on the occurrence of a parity error on the reassembly
ATM physical interface.
Set on the occurrence of a synchronization error on the
reassembly ATM physical interface.
Read as 0.
Reassembly/segmentation queue full condition.
Reassembly overflow. Indicates that a cell was lost due to a
FIFO buffer full condition.
Set on the occurrence of a host status queue full condition.
Set on the occurrence of a local status queue full condition.
Set on the occurrence of a host free buffer queue empty
condition.
Set on the occurrence of a local free buffer queue empty
condition.
Read as 0.
Segmentation underflow indicates that a scheduled cell
could not be sent due to lack of PCI bandwidth.
Indicates that the segmentation host status queue is full.
Indicates that the segmentation local status queue is full.
