The SyncMOS SM59264 integrates 64KB flash program memory and 64KB data flash.
This mcu may read data from data flash (address 0x300~0xFFFF) by instruction MOVX.
I tried using uVision to simulate this mcu. But I found that the uVision doesn't support memory download function so that I could't load a binary file to external memory.
What should I do if I wanna use uVision to simulate SM59264 ?
At least for ARM you can use load command in debbuger to load data to external or simulated memory.
