3 REGISTER & MEMORY MAP
As shown in the
addressing 64K bytes of memories and I/O regis-
ters.
The available memory locations consist of 128
bytes of register location, 256 bytes of RAM and
up to 8Kbytes of user program memory. 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.
