Register and memory map

Register and memory map

Caution:

As shown in Figure 5, the MCU is capable of addressing 64 Kbytes of memories and I/O

registers.

The available memory locations consist of 128 bytes of register locations, up to 2 Kbytes of

RAM and up to 60 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.

Memory locations marked as “Reserved” must never be accessed. Accessing a reserved

area can have unpredictable effects on the device.
