2.2.4 Special Test Mode
This special expanded mode is primarily intended or production testing. The user can access a number
of special test control bits in this mode. Reset and interrupt vectors are fetched externally from locations
$BFC0–$BFFF. A switch can be made from this mode to other modes under program control.
2.3 Memory Map
Figure 2-1 illustrates the memory map for both normal modes of operation (single-chip and
expanded-multiplexed), as well as for both special modes of operation (bootstrap and test).
In the single-chip mode, the MCU does not generate external addresses. The internal memory
locations are shown in the shaded areas, and the contents of these shaded areas are explained
on the right side of the diagram.
In expanded-multiplexed mode, the memory locations are basically the same as in the single-chip
mode except that the memory locations between shaded areas are for externally addressed
memory and I/O.
The special bootstrap mode is similar to the single-chip mode, except that the bootstrap program
ROM is located at memory locations $BF00–$BFFF, vectors included.
The special test mode is similar to the expanded-multiplexed mode except the interrupt vectors are
at external memory locations.
2.3.1 Control and Status Registers
Figure 2-2 is a representation of all 64 bytes of control and status registers, I/O and data registers, and
reserved locations that make up the internal register block. This block may be mapped to any
4-K boundary in memory, but reset locates it at $0000–$003F. This mappability factor and the default
starting addresses are indicated by the use of a bold 0 as the starting character of a register’s address.
