Physical Layer Interface Controller (PLIC)
13.5.8
All bits in this register are cleared on hardware or software reset.
The PLCR is an 8-bit register containing the configuration information for all four ports on the MCF5272.
13.5.9
All bits in these registers are read/write and are cleared on hardware or software reset.
The PnICR registers contain interrupt configuration bits for each of the four ports on the MCF5272.

In loopback mode, the respective port must be enabled (using
PnCR[ON/OFF]) along with the B1 and B2 channels (using PnCR[ENB1,
ENB2]) and the D channel (using PDRQR[DCNTI] when in IDL mode, for
instance). Also, if more than one of ports 1, 2, or 3 are programmed in
loopback mode, it is necessary to program the appropriate frame sync
function using the sync delay registers discussed in
