Bits Access Mnemonic Reset Description
D31:08 N/A Reserved N/A N/A
D07 R/W RPE100X 0 Reset PE100X module
Set this bit to 1 to reset the PE100X module,
which contains the 4B/5B symbol encipher/
decipher logic.
Must be set if not using 4B/5B logic.
D06 R/W FORCEQ 0 Force quiet
1 Transmit data is quieted, which allows the
cipher contents to be output.
0 (clear) Normal operation is enabled.
D05 R/W NOCIPH 0 No cipher
1 (enable) The raw transmit 5B symbols are
transmitted without ciphering.
0 (disable) Normal ciphering occurs.
D04 R/W DLINKF 0 Disable link fail
1 Disables the 330 ms link fail timer, allowing for
shorter simulations.
0 (clear) Normal operation occurs.
D03 R/W RPE10T 0 Reset PE10T module
Set this bit to 1 to reset the PE10T module. This
module converts the MII nibble-streams to the
serial bit stream for ENDEC transceivers.
Must be set if not using the PE10T module.
