Modes 1, 2, and 3 (EXPE = 1): In modes 1, 2, and 3 (when EXPE = 1), port 3 pins automatically
function as data I/O pins. The port 3 pin functions are shown in figure 8.10.
Modes 2 and 3 (EXPE = 0): In modes 2 and 3 (when EXPE = 0), port 3 functions as host
interface data bus I/O pins (HDB7 to HDB0) or as I/O ports. When the HI12E bit is set to 1 in
SYSCR2 and a transition is made to slave mode, port 3 functions as the host interface data bus. In
slave mode, P3DR and P3DDR should be cleared to H'00. When the HI12E bit is cleared to 0, port
3 functions as an I/O port, and input or output can be specified on a bit-by-bit basis. When a bit in
P3DDR is set to 1, the corresponding pin functions as an output port, and when cleared to 0, as an
input port.
The port 3 pin functions are shown in figure 8.11.
