R_INCORRECT_SNP Word Format (06H)
This word is read-only and is maintained by the RALP
Field (Bits)
Description
R_INCORRECT_SNP
(15:0)
16-bit rollover count of cells with SNP errors. This is
the atmfCESHdrErrors counter from the CES
specification. Initialize to 0. Once initialized, do not
write to this word.
R_CELL_CNT Word Format (07H)
This word is read-only and is maintained by the RALP
Field (Bits)
Description
R_CELL_CNT
(15:0)
16-bit rollover count of received cells. This is the
atmfCESReassCells counter from the CES
specification. Initialize to 0. Once initialized, do not
write to this word.
R_ERROR_STKY Word Format (08H)
Receive sticky bits should be used for statistics gathering purposes only as there
is no means of clearing them without the possibility of missing an occurrence.
Initialize to 0.
Field (Bits)
Description
TRANSFER
(15)
This bit is read then written with the same value
each time the AAL1gator-8 receives a cell. This
feature allows the processor to determine if the
AAL1gator-8 was in the middle of a read then write
cycle when the processor cleared the other sticky
bits. To accomplish this each time the processor
wants to clear sticky bits, it should complement this
bit. Then, if an additional read of this bit showed it
to be the wrong value, then the AAL1gator-8 has
had its sticky word update interrupted.
CELL_RECEIVED
(14)
A cell was received.
