10 / 140 page  ST72104G, ST72215G, ST72216G, ST72254G 10/140 3 REGISTER & MEMORY MAP As shown in the Figure 4, the MCU is capable of addressing 64K bytes of memories and I/O regis- ters. The available memory locations consist of 128 bytes of register location, 256 bytes of RAM and up to 8Kbytes 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. IMPORTANT: Memory locations marked as “Re- served” must never be accessed. Accessing a re- served area can have unpredictable effects on the device. Figure 4.
