SATURN USER NETWORK INTERFACE FOR 2488 MBIT/S
ABRTE:
The Abort Packet Enable bit enables the generation of an interrupt due to the reception of an
aborted packet. When ABRTE is set to logic 1, the interrupt is enabled.
MAXLE:
The Maximum Length Packet Enable bit enables the generation of an interrupt due to the
reception of a packet exceeding the programmable maximum packet length. When MAXLE
is set to logic 1, the interrupt is enabled.
MINLE:
The Minimum Length Packet Enable bit enables the generation of an interrupt due to the
reception of a packet that is smaller than the programmable minimum packet length. When
MINLE is set to logic 1, the interrupt is enabled.
LOFV:
The LOFV bit gives the ATM Loss of Cell Delineation state. When LOFV is logic 1, an out of
cell delineation (LOF) defect has persisted for the number of cells specified in the LCD Count
Threshold register. When LOFV is logic 0, the RCFP has been in cell delineation for the
number of cells specified in the RCFP LCD Count Threshold register. The cell time period
can be varied by using the LCDC[10:0] register bits in the RCFP LCD Count Threshold
register.
OOFV:
The OOFV bit indicates the ATM cell delineation or packet out of frame alignment state.
When OOFV is logic 1, the cell delineation state machine is in the 'HUNT' or 'PRESYNC'
states and is hunting for the cell boundaries or the packet processor is in Idle state. When
OOFV is logic 0, the cell delineation state machine is in the 'SYNC' state (either Correction or
Detection mode) and cells are passed through the receive FIFO or the packet processor is
not in Idle state.
