3.4.3
Ports 1, 2, and 5 and part of port A function as address pins A
maximum 16-Mbyte address space. The initial bus mode after a reset is 8 bits, with 8-bit access to
all areas. If at least one area is designated for 16-bit access in ABWCR, the bus mode switches to
16 bits. A

used for address output.)
3.4.5
Ports 1, 2, and 5 and part of port A can function as address pins A
maximum 16-Mbyte address space, but following a reset they are input ports. To use ports 1, 2,
and 5 as an address bus, the corresponding bits in their data direction registers (P1DDR, P2DDR,
and P5DDR) must be set to 1, setting ports 1, 2, and 5 to output mode. For A
0 in bits 7 to 4 of BRCR. The versions with on-chip flash memory support an on-board
programming mode in which the flash memory can be programmed. The initial bus mode after a
reset is 8 bits, with 8-bit access to all areas. If at least one area is designated for 16-bit access in
ABWCR, the bus mode switches to 16 bits.
3.4.6
This mode operates using the on-chip ROM, RAM, and registers. All I/O ports are available.
Mode 6 supports a maximum address space of 64 kbytes.
3.4.7
This mode operates using the on-chip ROM, RAM, and registers. All I/O ports are available.
Mode 7 supports a 1-Mbyte address space.
The versions with on-chip flash memory support an on-board programming mode in which the
flash memory can be programmed.
