The MODE register 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.
Read anytime.
SMODN may only be written if SMODN = 0 (in special modes) but the
first write is ignored.
MODB, MODA may be written once if SMODN = 1; anytime if SMODN
= 0 but the first write is ignored and in special peripheral and reserved
modes cannot be selected.

For More Information On This Product,
while the MCU is in special peripheral mode as internal bus
conflicts between BDM and the external master can cause
improper operation of both functions.
