internal data memory addressing
The 512K bits of internal data memory can be accessed both from the CPU and through the host-port interface
(HPI). The CPU sees the internal data memory as 64K bytes, organized in eight columns, each 1 byte wide and
16K rows tall. The HPI addresses the same memory across four columns, each 1 half-word wide and 16K rows
tall (32K half-words total). Unlike the CPU, the HPI only has the capability to address the internal data in a
little-endian mode where the address of individual half-words grows in the same direction as the addresses of
the full words. See Figure 9 for the addressing example.
NOTE:
Bit 16 of the host-port address (pin HA15) is not used in the initial release of the device (it must be
driven high or low and not left floating).
