There are 55 programmable Input/Output ports (I/O ports) P0 to P3, P4_3 to P4_5, P5_0 to P5_4, P6, and P8_0 to
P8_6. Also, P4_6 and P4_7 can be used as input-only ports if the XIN clock oscillation circuit is not used.
Table 7.1 lists an Overview of Programmable I/O Ports.

Operation When
The PDi_j (j = 0 to 7) bit in the PDi (i = 0 to 6, 8) register controls I/O of the ports P0 to P3, P4_3 to P4_5, P5_0 to
P5_4, P6, and P8_0 to P8_6. The Pi register consists of a port latch to hold output data and a circuit to read pin
states.
Figures 7.1 to 7.10 show the Configurations of Programmable I/O Ports. Table 7.2 lists the Functions of
Programmable I/O Ports. Also, Figure 7.12 shows the PDi (i = 0 to 6 and 8) Registers. Figure 7.13 shows the Pi (i =
0 to 6 and 8) Registers, Figure 7.14 shows the P2DRR Register, Figure 7.15 shows the PMR Register, and Figure
7.16 shows Registers PUR0, PUR1, and PUR2.
Programmable I/O Ports
1. In input mode, whether an internal pull-up resistor is connected or not can be selected by registers
2. When the XIN clock oscillation circuit is not used, these ports can be used as the input-only ports.
1. Nothing is assigned to bits PD4_0 to PD4_2, PD4_6, and PD4_7.
