DESCRIPTION
Received Cells with Correctable 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 Correct-
able HEC Byte Error Count - Bytes 2 through 0 registers contain
the 32-bit expression for the number of cells (containing correct-
able 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 Correctable HEC Byte Errors.
NOTE:
If the number of cells with Correctable 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").
