PROGRAMMABLE I/O PORTS

3.4 Internal peripheral devices’ I/O functions (Ports P42, P5 to P8, P90 to P93 and P104 to P107)

Ports P42, P5 to P8, P90 to P93 and P104 to P107 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

φ1 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.”
