RESEM_ACTV:

The RESEM_ACTV bit indicates whether there are any active reassembles.

When RESEM_ACTV is logic one, the RALP is current reassembling one or

more CPAAL5_PDUs. When RESEM_ACTV is logic zero, no reassembles are

active.

PDUABI:

The PDUABI interrupt bit indicates when the RALP received a CPAAL5_PDU

with an forward abort indication (length field = 0).

CEXOVI:

The CEXOVI interrupt bit indicates when the RALP had to abort a transfer on the

Multipurpose Port due to an overflow. An overflow occurs during a cell transfer

when the RALP samples RFIFOFB low. CEXOVI is set high when an overflow

condition is detected.

RESEM_ACTI:

The RESEM_ACTI interrupt bit indicates when the RALP transitions into and out

of a state where it is reassembling packets. When RESEM_ACTI is high, a

transition has been made. The RESEM_ACTV bit indicates which state the RALP

is actually in.

RSOCI:

The RSOCI interrupt bit should only be used when operating with an external

PHY Layer device such as the PMC SUNI-PDH. When RSOCI is high, the

received receive start of cell (RSOC) indication on input RSOC was detected in

an unexpected location. In such an event, the RALP block starts accumulating a

new cell and discards any residue bytes from the previous incomplete cell.

PTIDI:

The PTIDI interrupt bit indicates the reception of a cell with a PTI field equal to

110B or 111B. When PTIDI is high, the RALP has received one or more cells

with a PTI field equal to 110B or 111B.

F5OAMDI:

The F5OAMDI interrupt bit indicates the reception of a F5 OAM cell. When

F5OAMDI is high, the RALP block has received one or more F5 OAM cells.

OVPDUI:

The OVPDUI interrupt bit indicates that the RALP block has detected a

CPAAL5_PDU length violation. If OVPDUI is high, the RALP block has
