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.

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.
Description
100X
Transmit data is quieted, which allows the cipher
contents to be output.
(clear) Normal operation is enabled.
(enable) The raw transmit 5B symbols are transmitted
without ciphering.
(disable) Normal ciphering occurs.
Disables the 330 ms link fail timer, allowing for
shorter simulations.
(clear) Normal operation occurs.
