in $00000000-$0000003F
Bootstrap For writing (Prog RAM):
ROM $00000000-$000003FF
Note: Bootstrap ROM is at $00000000-$0000003F, PRAM becomes write-only
in Bootstrap modes.
After the bootstrap program executes, the chip reverts to Mode 0
(from Bootstrap Modes 4 or 6) or to Mode 1 (from Bootstrap Modes
5 or 7), and program execution begins at location $00000000 in
internal PRAM.
