Physical Layer Interface Controller (PLIC)
13.5.18 GCI C/I Channel Transmit Status Register (PGCITSR)
All bits in this register are read only and are cleared on hardware or software reset.
The PGCITSR register is an 8-bit register containing the C/I channel status bits for each of the four
transmit ports on the MCF5272.
