Received Cells with

Error Count[31:24]
TYPE
RUR
DESCRIPTION
Received Cells with Uncorrectable HEC Byte Error
Count[31:24]:
These RESET-upon-READ bit-fields, along with that within the
"Receive ATM Cell Processor Block - Receive Cells with Uncor-
rectable HEC Byte Error Count - Bytes 2 through 0" registers
contain the 32-bit expression for the number of cells (containing
"Uncorrectable" HEC byte errors) that have been received since
the last read of these registers.
This particular register byte contains the MSB (Most Significant
Byte) of this 32-bit value for the number of Received ATM cells
with Uncorrectable HEC Byte Errors.
NOTE:
If the number of cells with "Uncorrectable HEC Byte
Errors" reaches the value "0xFFFFFFFF" then these
registers will saturate to and remain at this value (e.g., it
will not overflow to "0x00000000").

Count[23:16]:
These RESET-upon-READ bit-fields, along with that within the

tain the 32-bit expression for the number of cells (containing

the last read of these registers.
NOTE:
If the number of cells with "Uncorrectable HEC Byte
Errors" reaches the value "0xFFFFFFFF" then these
