256 bytes Stack
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.
IMPORTANT: Memory locations marked as “Re-
served” must never be accessed. Accessing a re-
seved area can have unpredictable effects on the
device.
