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
IL) 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).
