FREEDM 84A1024L ASSP Telecom Standard Product Data Sheet
Description
packets must be identified by putting a unique CI in the non-
sequenced table based on DLCI. See Table 42 for details.
A corrupt CI lookup record consists of 1 entry per HDLC channel.
(For corrupt CI lookup, bits [21:12] of the lookup key are interpreted
as an HDLC channel number regardless of the setting of the
CI_LOOKUP_CHAN bit.) A datagram marked as corrupted will result
in an index to the corrupt CI lookup record. See Table 43 for details.
LSB Record Status. Upon initialization, S/W must write this field to
0 for correct operation of the chip.
Note – ECC must be disabled when these locations are read from
and written to by S/W.
X
MSB Record. Upon initialization, S/W must write this field to 0 for
correct operation of the chip.
Used by hardware.
LSB Record Freelist record. Each entry points to the location of an
unoccupied LSB record with each LSB record comprising 128
address locations. When the RS_DRAMC status register bit
FPP_INIT is set, internal logic writes a unique 15-bit pointer value to
each of the 32k freelist locations (pointer values ranging from 40h to
7FFFh). If the RS_DRAMC status register bit FPP_INIT is not set,
and has not been set since initialization of the device, then the
microprocessor must populate the LSB record freelist as the internal
logic will not have been invoked to do so. See Table 46 for details.
