7.
There are 71 programmable Input/Output ports (I/O ports) P0 to P3, P4_3 to P4_5, P5 to P8 and P9_0 to P9_3. 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 9) register controls I/O of the ports P0 to P3, P4_3 to P4_5, P5 to P8
and P9_0 to P9_3. The Pi register consists of a port latch to hold output data and a circuit to read pin states.
Figures 7.1 to 7.11 show the Configurations of Programmable I/O Ports. Figure 7.12 shows the Configuration of
I/O Pins. Table 7.2 lists the Functions of Programmable I/O Ports. Also, Figure 7.13 shows the PDi (i = 0 to 9)
Registers. Figure 7.14 shows the Pi (i = 0 to 9) Registers, Figure 7.15 shows the P2DRR Register, Figure 7.16
shows the PMR Register, and Figure 7.17 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.
