Technical Data
In single chip operating mode, the MC68HC11P2 microcontroller has no
external address or data bus. Ports B, C, F, and the R/W pin are
available for general-purpose parallel I/O.
In expanded operating mode, the MCU can access a 64kbyte physical
address space. The address space includes the same on-chip memory
addresses used for single chip mode, in addition to external memory and
peripheral devices.
The expansion bus is made up of ports B, C, and F, and the R/W signal.
In expanded mode, high order address bits are output on the port B pins,
low order address bits on the port F pins, and the data bus on port C. The
R/W/PG7 pin signals the direction of data transfer on the port C bus.
Special test, a variation of the expanded mode, is primarily used during
Motorola’s internal production testing; however, it is accessible for
programming the CONFIG register, programming calibration data into
EEPROM, and supporting emulation and debugging during
development.
