8 / 158 page ST72589BW, ST72389BW 8/158 1.3 REGISTER & MEMORY MAP As shown in the Figure 3, 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, up to 1Kbyte of RAM, 60 bytes of LCD RAM and up to 24Kbytes of user pro- gram 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. Figure 3. Memory Map Table 2.
