1.4 REGISTER & MEMORY MAP
As shown in
dressing 64K bytes of memories and I/O registers.
The available memory locations consist of 192
bytes of register location, up to 512 bytes of RAM
and up to 16K bytes of user program memory. The
RAM space includes up to 64 bytes for the stack
from 0100h to 013Fh.
