Section 3 MCU Operating Modes
3.4.6
Ports 1, 2, and 5 and part of port A 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. For A
A
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.
3.4.7
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.
3.5
The pin functions of ports 1 to 5 and port A vary depending on the operating mode. Table 3.3
indicates their functions in each operating mode.
