10 / 172 page ST72260Gx, ST72262Gx, ST72264Gx 10/172 3 REGISTER & MEMORY MAP As shown in Figure 5, the MCU is capable of ad- dressing 64K bytes of memories and I/O registers. The available memory locations consist of 128 bytes of register location, 256 bytes of RAM and up to 8 Kbytes of user program memory. The RAM space includes up to 128 bytes for the stack from 0100h to 017Fh. The highest address bytes contain the user reset and interrupt vectors. The Flash memory contains two sectors (see Fig- ure 5) mapped in the upper part of the ST7 ad- dressing space so the reset and interrupt vectors are located in Sector 0 (F000h-FFFFh). The size of Flash Sector 0 and other device op- tions are configurable by Option byte (refer to Sec- tion 15.1 on page 162). IMPORTANT: Memory locations marked as “Re- served” must never be accessed. Accessing a re- seved area can have unpredictable effects on the device. Related Documentation AN 985: Executing Code in ST7 RAM Figure 5.
