A[20:16] of the BGA package always functions as EMIF address pins and they cannot be reconfigured for any other function.

3.6.3

Parallel Port Signal Routing

The 5507 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 5507 routes the parallel port signals as shown in Figure 3-5.

Figure 3-5 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 is used with HPI or GPIO. Figure 3-6 summarizes the use of the

parallel port signals for memory interfacing.
