This section contains information about the modes that define
MC68HC11P2 operating conditions, and about the on-chip memory that
allows the MCU to be configured for various applications.
The values of the mode select inputs MODB and MODA during reset
determine the operating mode. Single chip and expanded modes are the
normal modes. In single chip mode only on-board memory is available.
Expanded mode, however, allows access to external memory. Each of
these two normal modes is paired with a special mode. Bootstrap, a
variation of the single chip mode, is a special mode that executes a
bootloader program in an internal bootstrap ROM. Test is a special
mode that allows privileged access to internal resources.
