Eight possible operating modes determine the operating configuration of
the MC68HC912D60A. Each mode has an associated default memory
map and external bus configuration. After reset, most system resources
can be mapped to other addresses by writing to the appropriate control
registers.
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.
