Eight possible operating modes determine the operating configuration of
the MC68HC912DT128A. Each mode has an associated default
memory map and external bus configuration.
The operating mode out of reset is determined by the states of the
BKGD, MODB, and MODA pins during reset.
The SMODN, MODB, and MODA bits in the MODE register show current
operating mode and provide limited mode switching during operation.
The states of the BKGD, MODB, and MODA pins are latched into these
bits on the rising edge of the reset signal.
