Physical Layer Interface Controller (PLIC)
13.5.16 GCI C/I Channel Receive Registers (P0GCIR–P3GCIR)
All bits in these registers are read only and are cleared on hardware or software reset.
The PnGCIR registers contain the received C/I bits for one of each of the four ports on the MCF5272.

Full. This bit is set by the C/I channel controller to indicate to the CPU that new C/I channel data
has been received and is available for processing. It is automatically cleared by a CPU read. The
clearing of this bit by reading this register also clears the aperiodic GCR interrupt.
value is received in two successive frames, it is interpreted as being valid and is passed on to the
CPU, via this register. A maskable interrupt is generated when data is written into any of the four
available positions.
