Figure 18-46. RFIFO Diagram
The detailed behavior of the pop next data pointer and receive next data pointer is described in the example
shown in
where an RFIFO with 16 entries is shown for clarity of explanation, the actual
hardware implementation has only four entries. In this example, RFIFO
n
with 16 entries is shown in
sequence after popping or receiving entries.

All RFIFO entries are memory mapped and the entries addressed by these pointers
can have their absolute addresses calculated using POPNXTPTR and RFCTR.
