The MCF5272 PLIC provides two sets of D-channel arbitration control pins:
Because pin set 1 connects ports 1, 2, and 3, these ports do not have D-channel arbitration control signals.

This section describes the GCI/IDL block.

The maximum data rate received for each GCI/IDL port is 144 Kbps: the sum of two 64-Kbps B channels
and one 16-Kbps D-channel. Frames of B
bits). Frames of D-channels are packed together to form bytes. For channels B and D, this requires CPU
service at a 2-KHz rate, because it requires four frames to fill the 32-bit B-channel register and the 8-bit
D-channel register.
The CPU should service the B1 and B2 registers once every 500 μS. Overrun conditions can be avoided
only if the CPU services these registers in a timely manner.
The MCF5272 has 4 GCI/IDL interfaces. Thus the theoretical maximum is twelve 32-bit data registers to
be read. For most applications the typical number is less.
