Note: The single flash block address structure for doing as well as program ROM flash.
1.2 Data Memory
The SM79164 has 4K bytes on-chip RAM, 256 bytes of it are the same as general 8052 internal memory structure while the
expanded 3840 bytes on-chip RAM can be accessed by external memory addressing method (by instruction MOVX), or by
âBank mapping direct addressing modeâ as described in page 8.
