3-CHANNEL DS3/E3/STS-1 TO STS-3/STM-1 MAPPER IC DATA SHEET
Receive ATM Cell Processor Block – Receive ATM Cells with Uncorrectable HEC Byte Error Count
Register – Byte 1 (Address = 0xN736)
Receive ATM Cell Processor Block – Receive ATM Cells with Uncorrectable HEC Byte Error Count
Register – Byte 0 (Address = 0xN737)
3. It will NOT correct the “Single-Bit” Error within this particular ATM cell. In fact, unless the Receive ATM
Cell Processor block is configured otherwise, it will discard this particular ATM cell.
Note:
Receive ATM Cell Processor Block – Receive Discarded ATM Cell Count – Byte 3 (Address = 0xN72C)
Receive ATM Cell Processor Block – Receive Discarded ATM Cell Count – Byte 2 (Address = 0xN72D)
Receive ATM Cell Processor Block – Receive Discarded ATM Cell Count – Byte 1 (Address = 0xN72E)
Receive ATM Cell Processor Block – Receive Discarded ATM Cell Count – Byte 0 (Address = 0xN72F)

Whenever the Receive ATM Cell Processor block discards ATM cells for “Uncorrectable HEC Byte” errors it will
also increment the “Receive ATM Cell Processor Block – Receive Discarded ATM Cell Count” Registers. These
registers are also 32-bit RESET-upon-READ registers that reside at Address Locations 0xN72C through
0xN72F. The bit format of these registers is presented below.
