Notes on H8S/2695
1. Notes on P35 Pin Functions (SCK1, SCK4) in H8S/2695
The following restrictions apply to the functions of P35 (SCK1, SCK4) in the H8S/2695. The
functions indicated by *2 below cannot be used in the H8S/2695, and these combinations must not
be set.

Notes: 1. The output type is normally NMOS push-pull output, but NMOS open-drain output when P35ODR = 1.
2. These combinations must not be set.
3. If SCK1 and SCK4 are used as input (clock input) pins on the H8S/2695, P35DDR must be cleared
to 0.
2. Notes on H8S/2695 Development (Using H8S/2633 Emulator Chip)
The H8S/2695 is not equipped with an I2C bus function and output from pins 34 and 35 is CMOS
output (unless P34ODR or P35ODR is set to 1, respectively). These pins are used for NMOS
push-pull output on the H8S/2633 emulator chip, so the output characteristics of these pins are
different than is the case with the H8S/2695. If it is necessary to use pins 34 and 35 for CMOS
output, use an appropriate resistance to pull up pins 34 and 35 of the H8S/2633 emulator chip.
