PROGRAMMABLE I/O PORTS

3.4 Internal peripheral devices’ I/O functions (Ports P42 and P5 to P8)

Ports P42 and P5 to P8 also function as I/O pins for the internal peripheral devices. Table 3.4.1 lists

correspondence between each port and internal peripheral devices’ I/O pin. For internal peripheral devices’

I/O functions, refer to the corresponding functional description. For the clock

φ 1 output pin, refer to chapter

“12. CONNECTING EXTERNAL DEVICES.” For the sub-clock oscillation circuit’s I/O pins, refer to chapter

“14. CLOCK GENERATING CIRCUIT.”
