Notes: 1. NMOS open-drain output when P35ODR = 1.
2. NMOS open-drain output regardless of P35ODR.
3. Not used in the H8S/2378 0.18μm F-ZTAT Group, H8S/2377, H8S/2375, and
H8S/2373.
• P34/SCK0/SCK4/SDA0
The pin function is switched as shown below according to the combination of bit ICE in
ICCRA of I
