MDA — Mode Select A Bit
After RESET is released, the mode select pins revert to their alternate
functions, described in
Reference, and Standby Power (MODA/LIR and
no longer influence the MCU operating mode.
The operating mode determines memory mapping and whether memory
is addressed on-chip or off-chip.
M68HC11K4 Family and M68HC11KS Family memory maps for each of
the four modes of operation. Memory locations for on-chip resources are
the same for both expanded and single-chip modes.
mode from special to normal, but not vice versa. To switch from a
special mode to a normal mode, write to the access-limited registers
(see
The mode select A bit reflects the status of the MODA input pin at the
rising edge of RESET. Software can change the MDA bit only while
the SMOD bit is set, effectively switching the operating mode between
special bootstrap and special test modes. Once the SMOD bit is clear,
the MODA bit is read-only and the operating mode cannot be changed
without going through a reset sequence.
