the regular system vectors while BDM is active. While BDM is active, the
user memory from $FF00 to $FFFF is not in the map except through
serial BDM commands.
MODE controls the MCU operating mode and various configuration
options. This register is not in the map in peripheral mode
SMODN, MODB, MODA — Mode Select Special, B and A
These bits show the current operating mode and reflect the status of
the BKGD, MODB and MODA input pins at the rising edge of reset.
SMODN is Read anytime. May only be written in special modes
(SMODN = 0). The first write is ignored;
MODB, MODA may be written once in Normal modes (SMODN = 1).
Write anytime in special modes (first write is ignored) – special
peripheral and reserved modes cannot be selected.
