Physical Layer Interface Controller (PLIC)
13.5.12 GCI Monitor Channel Receive Registers (P0GMR–P3GMR)
All bits in these registers are read only and are initialized to 0x00FF on hardware or software reset.
PnGMR are 16-bit registers containing the received monitor channel bits for each of the four receive ports
on the MCF5272.
A byte of monitor channel data received on a certain port is put into an associated register using the format
shown in
registers.
