Zarlink Semiconductor Inc.
Indicates the total number of bits that are used to decode the
look-up address for port A. 0001h = 1 bit used, FFFFh = 16 bits
used. When subtracted from vci_n, this indicates the number
of VPI bits used.
MT90503
Type
Bits 19:4 of the address of the look-up table for port A.
RW
Counts the number of cells lost due to fifo overflows. This
includes the output fifos from the look-up engine to the: RX
SAR, ports TXA, TXB, TXC.
126
Indicates the number of VCI bits used to
decode the look-up address for port A.
