There are 41 programmable Input/Output ports (I/O ports) P0 to P2, P3_0, P3_1, P3_3 to P3_5, P3_7, P4_3 to P4_5,
and P6. Also, P4_6 and P4_7 can be used as input-only ports if the XIN clock oscillation circuit is not used, and the
P4_2 can be used as an input-only port if the A/D converter is not used.

Operation When
The PDi_j (i = 0 to 4, 6, j = 0 to 7) bit in the PDi register controls I/O of the ports P0 to P2, P3_0, P3_1, P3_3 to
P3_5, P3_7, P4_3 to P4_5, and P6. The Pi register consists of a port latch to hold output data and a circuit to read
pin state.
Figures 7.1 to 7.7 show the Configurations of Programmable I/O Ports. Table 7.2 lists the Functions of
Programmable I/O Ports. Also, Figure 7.9 shows the PDi (i = 0 to 4 and 6) Registers. Figure 7.10 shows the Pi (i =
0 to 4 and 6) Registers, Figure 7.11 shows the Registers PUR0 and PUR1 and Figure 7.12 shows the PMR Register.
Programmable I/O Ports
1. In input mode, whether the internal pull-up resistor is connected or not can be selected by the PUR0
2. When the A/D converter is not used, these ports can be used as the input port only.
3. When the XIN clock oscillation circuit is not used, these ports can be used as the input port only.
1. Nothing is assigned to bits PD3_2, PD3_6, PD4_0 to PD4_2, PD4_6, and PD4_7.
