Note: The single flash block address structure for doing the ISP function to the on-chip data flash as well as
program ROM flash.
1.2 Data Memory
The SM59264 has 1K bytes on-chip RAM, 256 bytes of it are the same as general 8052 internal memory structure while the
expanded 768 bytes on-chip RAM can be accessed by external memory addressing method (by instruction MOVX), or by
‘Bank mapping direct addressing mode’ as described in page 9. The SM59264 also has 64K bytes data flash embedded in.
The contents of data flash can be erased or programmed by software control and can be read by MOVX instruction. User can
use MOVX instruction to access internal RAM, internal data flash or external memory by setting OME and DFEN. The differ-
ent setting of OME and DFEN will map to different memory block.
