HEC Error Mask
R/W
0x00
The Transmit Cell Processor block always XORs contents of this register with
the contents of the HEC byte (within each “outbound” ATM cell). This
“XORed” value is then written back into the “HEC” byte field, within each
“outbound” ATM cell; prior to transmission. Setting any of these bit-fields to
“1” introduces error in that specific bit, within each “outbound” HEC byte.
Register must be set to 0x00 for normal operation,
