3.5.3 Parallel Port Signal Routing

The 5506 allows access to 16-bit-wide (read and write) or 8-bit-wide (read only) asynchronous memory and

16-bit-wide SDRAM. For 16-bit-wide memories, EMIF.A[0] is kept low and is not used. To provide as many

address pins as possible, the 5506 routes the parallel port signals as shown in Figure 3−6.

Figure 3−6 shows the addition of the A

′[0] signal in the BGA package. This pin is used for asynchronous

memory interface only, while the A[0] pin can also be used with the GPIO. Figure 3−7 summarizes the use

of the parallel port signals for memory interfacing.
