8 / 132 page ST7263B 8/132 3 REGISTER & MEMORY MAP As shown in Figure 4, the MCU is capable of ad- dressing 64 Kbytes of memories and I/O registers. The available memory locations consist of up to 512 bytes of RAM including 64 bytes of register lo- cations, and up to 16K bytes of user program memory in which the upper 32 bytes are reserved for interrupt vectors. 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 noted “Re- served” must never be accessed. Accessing a re- served area can have unpredictable effects on the device. Figure 4. Memory Map * Program memory and RAM sizes are product dependent (see Table 1, "Device Summary") Table 3.
