The available memory locations consist of 128 bytes of register locations, up to 1 Kbytes of RAM and up to 32 Kbytes of user program memory. The RAM space includes up to 256 bytes for the stack from 0100h to 01FFh. The highest address bytes contain the user reset and interrupt vectors. Caution: Memory locations marked as ‘reserved’ must never be accessed. Accessing a reserved area can have unpredictable effects on the device. Figure 4.
