3 REGISTER & MEMORY MAP
As shown in
dressing 64 Kbytes of memories and I/O registers.
The available memory locations consist of up to
512 bytes of RAM including 64 bytes of register lo-
cations, and up to 16K bytes of user program
memory in which the upper 32 bytes are reserved
for interrupt vectors. The RAM space includes up
to 128 bytes for the stack from 0100h to 017Fh.

Description
01BF/023Fh
The highest address bytes contain the user reset
and interrupt vectors.
IMPORTANT: Memory locations noted “Re-
served” must never be accessed. Accessing a re-
served area can have unpredictable effects on the
device.
