Port 5

Port 5 is a general I/O port also functioning as an I

2C bus interface I/O pin, an A/D trigger input

pin, and a wakeup interrupt input pin. Each pin of the port 5 is shown in figure 9.4. The register

setting of the I

2C bus interface has priority for functions of the pins P57/SCL and P56/SDA. Since

the output buffer for pins P56 and P57 has the NMOS push-pull structure, it differs from an output

buffer with the CMOS structure in the high-level output characteristics (see section 23, Electrical

Characteristics).
