CFIFO, D0FIFO and D1FIFO are port registers that are used to read data from the FIFO buffer
memory and writing data to the FIFO buffer memory.
There are three FIFO ports: the CFIFO, D0FIFO and D1FIFO ports. Each FIFO port is configured
of a port register that handles reading of data from the buffer memory and writing of data to the
buffer memory, a select register that is used to select the pipe assigned to the FIFO port, a control
register, and registers used specially for port functions (an SIE register used exclusively for the
CFIFO port and a transaction counter register used exclusively for the DnFIFO port).
These registers are initialized by a power-on reset or a software reset.

Notes: 1. The DCP can access the buffer memory only through the CFIFO port. Accessing the

4. Registers configuring a FIFO port do not affect other FIFO ports.
5. The same pipe should not be assigned to two or more FIFO ports.
6. There are two sorts of buffer memory states: the access right is on the CPU side and it
