Notes 1. In the case of the 4 KB, this is about 3 KB when the self-programming function and data flash function are

used. (For details, see CHAPTER 3)

2. Only the constant-period interrupt function when the low-speed on-chip oscillator clock (f

) is selected.

3. The number of PWM outputs varies depending on the setting of channels in use (the number of masters

and slaves). (6.9.3 Operation as multiple PWM output function).
