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 2Kbytes of RAM,
up to 256 bytes of data EEPROM and up to
60Kbytes 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.
