Mode 2: In mode 2 (expanded mode with on-chip ROM enabled), port 1 can provide lower
address output pins and general input pins. Each pin becomes a lower address output pin if its
P1DDR bit is set to 1, and a general input pin if this bit is cleared to 0. Following a reset, all pins
are input pins. To be used for address output, their P1DDR bits must be set to 1. Figure 7.3 shows
the pin functions in mode 2.
Mode 3: In mode 3 (single-chip mode), the input or output direction of each pin can be selected
individually. A pin becomes a general input pin when its P1DDR bit is cleared to 0 and a general
output pin when this bit is set to 1. Figure 7.4 shows the pin functions in mode 3.
