CHAPTER 4 INTERNAL REGISTERS
R/W
R Indicates a parity error in the HTT & control memory.
R Indicates a parity error in the cell buffer memory.
R Indicates an overrun of the input FIFO at the reception side.
R Indicates an abnormal status in the pointer that manages the queue.
R Indicates an abnormal status in the cast counter that manages
multi-cast count.
R/W Indicates that a cell has been discarded because the area for
storing data has run short in the cell buffer memory.
R/W Indicates that a cell has been discarded because the area of the
control memory that manages the queue of the HTT & control
memory has run short. This may occur if the average broadcast
count exceeds 2.
R/W Indicates an HEC error or CRC error in a received cell.
If the HM bit of the MODE register is "1", the HEC error is not
indicated because the HEC error cell is not discarded.
R/W Indicates a header translation error.
R/W Indicates that a cell has been discarded because a threshold value,
service class, or logical output port number of the EXTHMS register
is exceeded.
R/W Indicates that CTMEMEMP overflowed.
